114 "ENDEAVOUR" SCIENTIFIC RESULTS. 



anal fins are slightly enlarged, adherent, and strongly spinate. 

 The lateral line is arched anteriorly, but descends to the median 

 line of the body and runs along the middle of the caudal 

 peduncle. 



Dorsal spines of moderate strength and coarsely cariuate ; the 

 second is the longest, the others decreasing evenly backwards. 

 The rays are simple, and increase in length to about the 

 eighteenth. Anal similar to the dorsal. Ventral rounded, 

 inserted a little in front of the pectoral ; the spine is long and 

 carinate and the rays are divided. Pectoral short and broadly 

 rounded, its rays simple. Caudal a little rounded, or with the 

 outer rays very slightly produced. 



Colour. Brownish. Some specimens have more or less 

 numerous small brown ocelli on the dorsal and anal rays. Iris 

 golden. The membrane behind the maxillaries black. 



Described from a specimen 207 mm. long from the snout to 

 the end of the caudal fin. Twenty-eight others, 145-205 mm. 

 long, vary a little in the form of the body, the back being more 

 abruptly elevated in some than in others. The depth at the 

 origin of the dorsal may be either 1.49 or 1.70 in the length to 

 the hypural, and some specimens have a small pa,tch of 

 microscopic, villous teeth attached to the skin behind the vomer, 

 which, however, are very different to the tnie A'omerine teeth of 

 Neocyttus or Allocyttus. 



Loc. Great Australian Bighr, Long. 12928'E., 350-450 

 fathoms ; 14th May, 1913. 



Genus ALLOCYTTUS, gen. >wv. 



Body compressed, covered with rather small scales with 

 strongly ctenoid margins which are turned outwards ; they are 

 imbricate on the sides and hinder half of the body only, those 011 

 the nape and abdomen being simply juxtaposed, angular, and 

 each having a small raised tubercle in its centre. Some enlarged 

 flat scales are irregularly arranged in two rows on the sides 

 below the pectorals ; none below the origin of the dorsal fin. 



Jaws very protractile, the intermaxillary processes received 

 into a broad oblong caviiy extending backwards to above the 

 middle of the orbits. Superficial bones of the head with 

 granules and course ridges, those of the operculurn forming a 

 radiating series. Preorbital of moderate width. Small teeth 

 in one or two series on the jaws and vomer ; palatines and 

 tongue toothless. A single dorsal fin with about six, rather weak 

 spines, and thirty-one rays. Anal with two or three spines, and 

 aboiit twenty-eight rays. Ventral with one spine and six rays. 

 Branchiostegals seven.
