    This paper deals with ecology and part of the Life history of the Chinese alligator. In making the investigation, the auther has paid visits to the Lower Yangtze basin and its adjacent territory during February-October in 1951, 1954, and 1956 in south Anhwei.The Chinese alligator inhabits the alluvial plain. During the growth and development of river, there are two seasonal periods in a year. The rainy season covering from April to October, and the dry season from October to March of the next year. During the dry season, one side of a broad sand swamp is an artifial dam, while the opposite is the natural bank, which may be gradually destroyed by the current in the rainy season year after year.During the rainy season, the water level is higher which serve as a shelter to the hidden alligator.The Chinese alligator is not only found along the basin of the lower Yangtze River, but also in south Anhwei districts along Chin-I-Kiang and Cheun-Ho River system. The plain is always sunk down by the tide, its surface being usually covered by a harder mud. A lot of burrows are distributed here and there. Each burrow has seveal holes. It is seaier to find out such burrows in the fall and winter, because the reeds are then cropped.Investigations showed that there were two types of burrows with respect to the sex of the alligator found inside. The male burrow is a simple tunnel with two openings, while the female's is more complicated.A longitudinal section of the female's burrow shows that the burrow is somewhat like a three-storied building. The differences in the level of diggings are considered as adaptations to different water levels.The following table presents burrow types in sexual diamorphism.The changes of water levels of the alluvial plain of definite regional river system may be related, according to our field examination, to the period of the animal's hibernation. The burrowed creature is coiled underground in 2m. deep during the winter season. The types of the burrows may be shown in the following table:In the wet season, the water level is about 8m. deep, just reaching.the surface of plain. This fact indicates that water is essential to the animal in the regulation of its physiological processes.The alligator mates in May and June, nesting at the end of June, laying The words "Doors'' and "Windows" adopted here are taken to indicate the various openings of the nests of the alligators.eggs in the July and August. The eggs measure 59 mm. in diameter. The shell is very hard, being ashy white in colour.The head and body length of the breeding adults as well as the number of eggs found in females may be given in following table:Other observations on the night movement during the breeding period may be shown as follows:

    1. On the basis of the preliminary studies from November, 1954 to March, 1955,further studies on the hibernation of mosquitoes were carried out in Changshafrom January to March, 1956. During this period tree holes, bamboo stumps, jars. earthern pots, fertilizer pits containing feces, basements, green-houses and mountaincaves were targets for the collection of hibernating mosquitoes each week. As aresult of this collection three species of mosquitoes hibernating during the winterwere newly discovered. Including the original four known species, Aedes albopictus,Aedes niveus, Culex fatigans, and Anopheles hyrcanus var. sinensis, which were foundin the preliminary study, there are seven in total representing five genera. 2. Aedes albopictus was confirmed to bibernate in the egg stage. Eggs werefound in earthern pots, jars, bamboo stumps of Phyllostachys mitis, tree holes ofLiquidambar formosana Hance, Evodic glauca Miq., Ilex purpurea var. oldhami Loes,Dalbergia sp., Albizzia kalkora Prain, Cinnamomum camphora Nees and Eberm. 3. Aedes niveus was again found to hibernate in the egg stage in the treeholes of Quercus sp., Quercus fabrei Hance, Quercus glauca Thunb, Ilex sp., Ilex pur-purea var. oldhami Loes, Liquidambar formosana Hance, Evodia officinalis Dode,Evodia glauca Miq., Spondias axillaris Roxb., Cinnamomum camphora Nees andEberm, Albizzia kalkora Prain, Hovenia dulcis Thunb, Dalbergia sp., Celtis sinensisPers, Ulmus parvifolia Jacq. 4. The larvae of second, third and fourth instars of Orthopodomyia anopheloideswere found in the tree holes of Liquidambar formosana Hance and Dalbergia sp.Whether Orthopodomyia anopheloides will actually hibernate in the larval stageneeds further observation for confirmation. 5. Armigeres obturbans was found to hibernate in the larval stage under thecover of grasses, leaves, twigs and so forth on the surface of water in fecal pits. 6. Culex hayashii was found to hibernate in the adult stage. Both male andfemale adults were caught in the mountain caves. The quantity of fat bodieswithin the female was noted and analysed. 7. Culex fatigans was again found to hibernate in the adult stage. Both maleand female adults were caught in tbe basements, greenhouses and mountain caves.But its chief shelter for hibernation was in mountain caves where the majority ofthis species was caught. Dissections showed that the quantity of fat bodies washigh for those adults which were caught in January and February while thosecaught in March showed a lower fat body content. After hibernation was over thefirst adults engorged with blood was caught on March 22nd. 8. The hibernation of Anopheles kyrcanus var. sinensis in adult stage was veri-fied. Female adults were caught chiefly in mountain caves. The condition of thewings, the development of ovaries as well as the quantity of fat bodies were notedand analyzed. After hibernation the first two females engorged with blood werecollected on March first. 9. The influence of temperature, humidity and light in the shelters where theadults of Culex hayashii, Culex fatigans and Ahopheles hyrcanus var. sinensis passedthe winter has been discussed.
