pace: on euselenops luniceps (cuv.).

by Adams and Reeve is, I think, rather doubtful : Bergh's description 

 and figures of Semper's shrivelled-up spirit specimen hardly tally with 

 those published of the (living) " Sainarang " one. A comparison of 

 the internal anatomy will however decide the question ; and this 

 comparison will now be possible, since I have recently been fortunate 

 enough, while collecting in Torres Straits, to meet with what is un- 

 doubtedly an example of Euselenops. 



On board the schooner " Dayspring," moored in Friday Island 

 Passage, one of my boys on a certain afternoon directed my attention 

 to ^ a peculiar ' fish ' which was swimming vigorously alongside the 

 ship. By the aid of a draw-bucket we succeeded in capturing the

strange object, which proved to be a specimen of Euselenops. I was 

 fortunately able to keep the animal alive in a tub of water on board 

 for some days, and thus had a good opportunity for observing its habits. 

 While in confinement it was very active : spending most of the time 

 (night as well as day) in creeping rapidly round and round the bottom 

 of the tub, and every now and then swimming about wildly for some 

 few minutes, with a curious undulating motion something like that of 

 a pleuronectid fish. While swimming it would often turn a complete 

 somersault. When at rest the body became much flattened out, and 

 even the excurrent siphon would then occasionally be obliterated, but
