188 "ENDEAVOUR" SCIENTIFIC RESULTS. 



Localities. P. fuscus is recorded from Monte Bello 

 Islands, West Australia. The type of P. nebulosum was 

 obtained at Murray Island, Torres Strait, and that of 

 P. wildii was said to have come from Moreton Bay, 

 Queensland. Other specimens in the Australian Museum 

 which I identify as P. fuscus are from New Britain and 

 the Solomon Islands.

D.iii/14, 9 ; A.iii/14 ; P.17 ; V.i/5 ; C.17. L. lat. 28/6 ; 

 about 34 rows of scales between the origin of the lateral 

 line and the hypural joint. 



Depth of body (15 mm.) 3-3 in the length to the 

 hypural joint (50) ; head (16) 3-1 in the same. Eye 

 (4-5) much longer than the snout (3), and 3-4 in the 

 head. Interocular space (2) 2-2 in the eye. Pectoral fin 

 (11-5) 1-3, caudal (13) 1-1, and depth of caudal peduncle 

 (7) 2-2 in the head. 



Body compressed, the head obtusely pointed. 

 Anterior nostril in a short tube, the posterior a simple 

 opening near the eye. Series of minute pores encircle 

 the eye, cross the nape, and extend around the pre- 

 orbital bone and mandible; they are prominent on the 

 preoperculum, where they are associated with short 

 tubes which open on the extreme margin of the bone 

 and form several small angles. Maxillary reaching back- 

 ward almost to below the middle of the eye. Large 

 cycloid scales cover the head, extending forward to the 

 interorbital space above, and onto the interoperculum 

 below; they are arranged in four rows on the cheeks. 



Two pairs of large canines on the front portion of 

 each premaxillary, followed by a row of conical teeth 

 on each side; a band of minute teeth covers the symphy- 

 sial area. Canines on each side of the mandible 

 anteriorly and one or two farther back on each side; an 

 inner band of microscopic teeth anteriorly and a single 

 row of larger ones which are more or less juxtaposed on 

 each side. An angular patch of microscopic teeth on the 

 vomer, and a rounded patch on the anterior portion of 

 each palatine bone.
