only sparingly punctured ; the middle part, indeed, is almost free from 

 punctures. Scutellum large, quite impunctate. Elytra only finely 

 and sparingly punctured, the punctures arranged almost in lines, the 

 sides towards the apex and the apex strigose. Pygidium strigose, but 

 shining. Under surface green ; sides of tlie breast with scanty pale 

 hairs and coarsely strigose, the centre smooth and shining. The me- 

 sosternal process very short and broad, densely pubescent along its 

 front. Front tibiae acutely tridendate. 



This species is allied to Getoiiia fulgida, Fab. (genus Erh^Jiipis, 

 Burm.), but is larger, without pale marks, and has the head 

 differently shaped. 



Though I have examined a series of ten individuals of this spe- 

 cies^ I see no indications of any external sexual distinctions. 



Geographical Distribution of Indian Freshwater Fishes. — Part I. 

 The Acanthopterygii, Spiny-rayed Teleostean Fishes. By 

 Francis Day, F.L.S., F.Z.S., &c. 



[Eead December 7, 1876.] 



DuEiNG comparatively recent times much interest has been mani- 

 nifested regarding the geographical distribution of the fauna of 

 India, and arguments have been adduced to demonstrate the 

 predominance in it of the Malayan or African element. 



As a small contribution to the facts which are being accumu- 

 lated, I propose a consideration of the distribution of the fresh- 

 water fishes, believing they must afford evidence upon which some 

 conclusions may be based. My limits will be Hindustan proper, 

 including the Punjab and Sind, as well as Ceylon, Assam, Burma, 

 the Andamans, and the Nicobars. 



The freshwater fishes consist : — 



(1) Of those which reside entirely in fresh water. 



(2) Of those which enter it from the sea for breeding or pre- 

 daceous purposes. 



The second will be briefly considered, and only when the spe- 

 cies belongs to a genus which likewise inhabits fresh water. In 

 such instances it will be necessary to trace out every species of 

 which the genus is composed.
