Notice of the " Etuet," a species of Tetraodon. 271 



consists of eleven rays, the anterior rays being the longest. 

 The anal fin, situated about half an inch behind the anus, 

 and opposite to the dorsal, is rather smaller in size, 1 inch 

 in length, by scarcely half an inch in breadth at the base, 

 and consists of eight rays. The caudal fin is 2 J inches in 

 length, and 1J inch in breadth when expanded, and is very 

 slightly rounded at its extremity. It appears to consist of 

 eight large or double rays, each dividing into two rays. 



A depressed fine line, faintly marked on the skin, sur- 

 rounds each orbit in an irregularly rounded manner, at the 

 distance of about half an inch from the orbit above, and of 

 a quarter of an inch below ; it sends off a short branch be- 

 tween the eye and pectoral fin, which runs downwards 

 towards the belly. A very little behind this, and at the 

 back part of the circle surrounding the orbit, on a line with 

 the upper part of the pectoral fin, a distinct depressed line 

 curves backwards and upwards ; (after giving off a branch 

 immediately in front of the fin which runs across the back 

 part of the head to join the line of the opposite side), and 

 runs backwards along the side of the fish to near the dorsal 

 fin, where it next curves downwards a little way ; and at 

 about half an inch behind this fin, it sends off a short branch 

 forwards towards the belly ; and from this point of division 

 it runs on to terminate at the centre of the base of the tail, 

 forming thus the lateral line of the fish. 



Whether this species may turn out to be the same as the 

 one briefly described by Mr Murray, I do not at present 

 know ; although I rather regret he has fixed on the some- 

 what trivial name of pustulatus, as a series of spots along 

 the side seems to be common to many species of this Genus ; 

 I shall therefore wait for more information before venturing 

 to give this specimen any other specific designation. 



Since this communication was read to the Society, I have 

 had a reply from the Eev. Mr Eobb, Old Calabar, to some of 

 my inquiries about this fish. Mr Eobb writes as follows : — 

 I I may say that native information about animals is often 

 very unreliable, though the best we can get. The Balloon 

 or Globe Fish, the Etuet (e-twet) is got in the river and
