become narrower and proceed, without coeca or convolutions, 
straight to the anus. The liver is elongated, flattened, narrow; 
it commences at a very short distance from the pericardium 
and is closely attached to the digestive canal. It terminates 
at a short distance from the anus; it is throughout divided 
by numerous transversal fissures; the colour is a pale yello- 
wish red. The gallbladder is elongated oval, a little shorter 
than the perieardium; it is situated near the pylorus, between 
the liver and the stomach; the duct is short and without cir- 
cumvolutions enters the duodenum. ‘The spleen is a small 
elongated gland, of a brownish erimson colour, in size near- 
ly equal to the gallbladder. It is situated between the liver 
and the duodenum, a short distance behind the pylorus. The- 
re is no airvessel. 
In the Catalogue of Malayan Fishes (Journ. As. Soc. Ben- 
gal, XVIII, p 1316), it has been shewn that the genus Q- 
phisternon MeCrrrranp, is partly founded on erroneous cha- 
racters, which, on being corrected, prove that supposed ge- 
nus to be identical with Symbranchus. Mr. MacCrerranp says 
that there are „fwo bands of teeth on the edges of the upper 
jaw”. But, from his own deseription and figure, it is evident 
that there is but one series. As regards the branchiostegous 
rays, Mr. McCrerranp writes (Apodal Fishes of Bengal, p 
197): „There are five or six short cartilaginous rays in either 
side of the branchial membrane.” Farther on, page 220: ”5 
short cartilaginous branchial rays:” The fact is, there are 
six osseous rays on each side, which terminate in filaments. 
Both the description and the figure of Ophisternon bengalen- 
sis MeCrerranp, contain errors, which cannot but mislead 
the reader who happens to have no access to specimens of 
the fish, from which Mr. MeCrerranp drew up his descrip- 
tion. 
Dr. P. Brreker in one of his admirable monographs (Bij-

den Indischen Archipel, p. 58), has pointed out the errors
