272 "ENDEAVOUR" SCIENTIFIC RESULTS. 



Depth of body 2 to 2| in the length, length of head 

 4 to 4f. Kostral hook not extending downwards as far 

 as level of posterior end of maxillary of ocular side. 

 Lower eye a little in advance of upper, diameter of which 

 is about 4 times interorbital width and 4^ to 5 in length 

 of head. Maxillary not reaching anterior edge of eye; 

 length of lower jaw of ocular side 3 to 3 in head ; a few 

 simple tentacles forming a fringe on lower lip of ocular 

 side. Teeth much smaller than in A. rostratus or A. 

 tudori. Gill-rakers rather small, about 10 on lower part 

 of anterior arch. Scales of ocular side ctenoid or 

 cycloid, denticulations, when present, large, but few in 

 number ; scales of blind side nearly all ctenoid, denticula- 

 tions weaker than those of ocular side; 88 to 92 scales 

 in a longitudinal series just above lateral line, 33 to 39 

 between lateral line and highest point of dorsal profile. 

 Lateral line with a slight curve anteriorly; no accessory 

 branch. Dorsal 74-75; longest rays about If in length 

 of head. Anal 50-51. Eight pectoral with 8 to 10 rays 

 (5 to 8 branched), equal to that of left side and If to 2 

 in length of head. Eight pelvic with 13 rays, extending 

 forward to meet tip of rostral hook, its anterior ray 

 inserted below anterior part of jaws of blind side, 

 posterior rays scaly on ocular side ; left pelvic with 3 to 4 

 rays, the first ray opposite space between eleventh and 

 twelfth of right pelvic. Caudal with 3/12/3 rays; 

 rounded. Caudal peduncle very short, the last rays of 

 the dorsal and anal fins being almost contiguous 'with 

 bases of outer caudal rays; depth 1^ to If in head. 

 Ocular side light brownish, with minute black dots 

 scattered over head, body, and fins ; blind side whitish. 



Hab. South Australia. 



Described from three specimens, 90-125 mm. in total 

 length. 



6. COLISTIUM, gen. nov. 



Close to Ammotretis, but olfactory laminae arranged 

 in pinnate form, radiating from a very short median 

 rachis. Gill-rakers numerous, small and rather stout. 

 Eays of dorsal and anal fins naked; a scaly sheath 

 covering basal parts of fin on ocular side. 



Two species from New Zealand.
