The results of morphological observations and measurements of 200 Chinese male adult mandibular alveolar arches are as follows: 1.The average measuremants of the mandibular arch depth and arch breadth are 4.62 cm and 5.03 cm respectively. 2.The shape of the arch can be either square or pointed depending upon whether the value of the arch/chord index is greater or smaller than 95. 3.There are four curved line equations for left-external,left internal,right- external and right-internal half arches computed from the plotted geometrical configuration.All errors are less than 0.001 cm,while the coefficients of co-relation are greater than 0.999.This proves that the result of this research work is success- ful. 4.The total area of the alveolar region of Chinese adult male mandibles is 12.15 cm~2 in average.

The branchiocraniums of Lcucisinc fishes consist of four parts,i.e., mandibular arch,hyoid arch,branchial arch and opercular bones,The names and numbers of all the bones belonging to these parts have been given in the present paper.The morphology and evolution of some bones of the branchiocranium have been described and disscussed.Bascd on the obscrvation,a comparision of the bones has been made among the genera belonging lo lhe subfamily.There are three patterns of urohyals in the subfamily accoading to their morphology,and three patterns of maxilla,etc.The morphology of maxilla arch adapts the feeding habits of the fishes.The maxilla arch developed very well in the cariovorous fishes,cspccially in Elopichthys bambusa,but not developed very well in the un-cari-vorous fishes.A key to the genera has been shown based on the morphology of the branchiocraniums of them. The present paper also deals with evolution of the phatryngeal bones and their teeth on thcm of Cyprinidae in China,cspccially of Leucisciscinac.

Pelteobagrus Fulvibraco is a species of small economic catfish dis- tributing all over the rivers and lakes of our country.It lives at the bottom of water.This paper gives a detailed description of its skull. The common skull characteristics of Siluriformes fishes closely related to their bottomliving have been further illustrated. According to the study,the skull of P.Fulvidraco consists of 126 bones(Neurocranium 37,Splanchnocranium 89:Mandibular arch 20, Hyoid arch 38,Branchial arch 31).It has no parietal,opisthotic and subopercular;but the cartilagious sympletic is present. There are a series of cone shaped teeth on the vomer,premaxillary and dentary,The maxillary has evolved short sticklike bone to support the barbels. The hyomandibular,quadrate,mesopterygoid and articular are well developed and they are formed a strongly stiffened contact between the upper jaw and the lower jaw and them in turn to the neurocranium. The preopercular and interopercular lose their premary function of protecting the gill,and they articulate soldly with the hyomandibular and quadrate as to powerfully suspend the low jaw to the hyomandihular and gradually to the neurocranium.

黄颡鱼是广布于我国各江河湖泊的一种习见小型经济鱼类,生活水流底层。其头骨共有126块;无顶骨、后耳骨和下鳃盖骨,有续软骨存在。犁骨、前颌骨、齿骨上都具铺石状牙齿;上颌骨、腭骨不具齿而异常特化成棒状小骨以支持触须。舌颌骨、方骨、中翼骨、外翼骨发育良好。前鳃盖骨失去鳃盖作用而参与悬器的形成。
