 ish. P. 11 ; D. 77 ; A. 44 ; C. 18 or 20 (according to Montagu).

 Cepholophis viride, Kaup, MS. 



Diayn. Anus situated towards the end of the proximal third part 

 of the length of the body. 



Descr. Head less round, more oval, and its length comprised 

 six or seven times in the total length. Dorsal fin beginning at the 

 tips of the pectorals. Body terminating in a moderately blunt tail, 

 but the caudal fin is less fully developed than that of the preceding 

 species. Colour green, with numerous fine blackish points which 

 cannot be seen by the naked eye. 



Total length 583 in. 



Length to the anus ....... 209 ,, 



To the beginning of the dorsal fin .... Iv22 ,, 



Length of head to the gill-opening .... 0-87 ,, 



P. 11 ; D. 87 ; A. 68 ; C. 10 == 1C5 vertical rays. (Richardson 

 gives precisely the same number of rays in the vertical fins, without 

 distinguisbing the caudal rays from the others. Pieinhardt reckons 

 168 vertical raj's.) 



The Paris Museum possesses a specimen received from Professor 

 Reinhardt. On it 1 have founded the generic character, since I 

 know G. imbcrhis only tlirough Yarrell's description and figure. 

 Pennant (in British Zoology, pi. 29,) gives a figure named on the 

 plate " Beardless Ophidium," but which is copied from Schneider, 

 who terms it Oph. chinense. It differs from the drawing of Mon- 

 tagu in the dorsal fin commencing further back, and in the shape 

 of the head. Rafinesque also (pi. 4, f. 4) gives a sketch of an Oph. 

 punctatum, which has a more acutely tapering tail than Pennant's 

 figure. Whether these constitute two distinct species, or whether 

 they belong to the same species, must be decided hereafter, since
