162 "ENDEAVOUR" SCIENTIFIC RESULTS. 



The maxillary reaches back to behind the level of the second 

 dorsal spine, but not to the orbital margin The nostrils open 

 in two fleshy papillae, on short stalks, near the margin of the 

 upper lip : they are separated by a space which is greater than 

 that between the orbits. There is a single row of minute teeth 

 projecting forward on the front of the premaxillaries ; these are 

 followed by much larger ones which are in two rows in front and 

 one on the sides, those of the second row being much the largest. 

 The mandibular teeth are similar to, but larger than the inner 

 premaxillary ones ; they are triserial anteriorly, becoming 

 uniserial behind, and the longest, which are in the third row, 

 are about two-thirds as long as the eye-opening. There is a 

 single fixed tooth on each side of the vomer, which is widely 

 separated from its fellow. Each palatine bone has two distinct 

 teeth anteriorly and three or four smaller ones farther back. 



First dorsal spine longest, very slender, and placed close 

 behind the tip of the snout ; it terminates in a short flap, and 

 extends backwards almost to the base of the third spine. Second 

 spine midway between the first and the level of the front margin 

 of the eye ; it is enveloped in skin, and has some short tentacles 

 projecting from the sides. Third and fourth spines extremely 

 slender and hair-like, and without dermal appendages, the base 

 alone being enveloped in skin ; the third is a little before the 

 highest point of the back, and the fourth is between the ends of 

 the humeral spines, A low, skinny tentacle, which is rather 

 nearer the fourth spine than the first ray, apparently represents 

 the fifth spine, but I find no trace of a sixth. Soft dorsal 

 originating between the posterior flaps of the gill-openings ; all 

 the rays are simple except the last which is divided from, the base 

 into two, and the fourth is the longest. The anal commences 

 below the fifth dorsal ray, and the fourth ray, which is the 

 longest, is about equal to that of the dorsal ; most of the rays 

 are bifurcate, and the last is also divided to the base. Caudal 

 rounded with all the rays branched. Pectorals quadrangular ; 

 the rays are simple with their tips free, and the last seven or 

 eight are thickened at their tips and normally bend forwards on 

 the lower surface of the fin. Ventrals inserted below the hinder 

 margin of the eye ; the spine is small and hidden in the skin, 

 and the first two rays are thickened and divided, the others 

 simple. 



Colour. Upper surface pale lilaceous brown, the dermal 

 filaments and tentacles darker. Lower surface white. Tongue 

 white with blackish, anastomosing lines anteriorly. 



Described from a single specimen, 184 mm. long from the 

 upper lip to the middle caudal rays. It is undoubtedly the type 

 of Ogilby's rinroloplihis latlcppx which was " described on
