8 THE VOYAGE OF H.M.S. CHALLENGER. 



eye a little in advance of the upper. Snout with three pointed projections in front of 

 the upper eye (at least in the adult). None of the fin rays produced. Pectoral of the 

 coloured side as long as the head, without snout. A series of distant large blackish spots 

 along the basal half of the dorsal and anal fins ; one or two similar spots on the basal 

 half of the caudal, and on the terminal portion of the tail. Pectoral with two or three 

 blackish transverse bands. In two very young specimens which appear to belong to the 

 same species the eyes are very close together, and there are no tentacles on the snout. 

 Length of specimen If to 3^ inches. Coast of Brazil. Station 122 ; 30 or 350 fathoms. 



Hipjjocampus guttulatus, Cuv. Station 122; 30 or 350 fathoms. 



Hippocampus villosvs, n. sp. (PI. I. fig. D). 



Dorsal fin with sixteen rays. Tubercles well developed, rather pointed, the most 

 prominent provided with bundles of filaments ; the whole upper surface, and especially 

 the top of the trunk, covered with similar filaments ; supraorbital spine slightly truncated, 

 and with its anterior portion slightly detached ; coronet of moderate height ; the length 

 of the snout is equal to the distance between the centre of the orbit and the gill-opening. 

 Uniform light coloured. Length of specimen 2^ inches. Ofi" Bahia, in 7 to 20 fathoms. 

 The figure represents the specimen twice its natural size. 



MonacantJius occidentalis, Gthr. Station 122 ; 30 or 350 fathoms. 

 Ostracion quadricornis, L. Station 122; 30 or 350 fathoms. 



4, Bermuda. 



The marine fish fauna of Bermuda does not exhibit any peculiarity, by which it may 

 be distinguished from that of the tropical Atlantic generally. No naturalist has paid 

 more attention to it than Mr J. Matthew Jones, who has collected the fishes round this 

 island for many years, and who has recently succeeded in obtaining several which hitherto 

 had escaped observation. Mr G. Brown Goode has published (1876) a Catalogue of the 

 Fishes of Bermuda, based chiefly upon the collections of the United States National 

 Museum. Probably in the course of years all the species found round the West Indian 

 Islands will be found to occur, at least occasionally, near Bermuda. 



In the following list those recently observed by Mr Jones are enumerated with those 

 collected by the naturalists of the Challenger : — 



Carcharias ohscuriis. 

 Mustelus IcBvis. 

 jEtobatis narinari. 

 Holocentruni longipmne. 



Serranus undidosus. 

 Serranus coronatus. 

 Hhypticus saponaceus. 

 Mesoprion chrysurus.
