commences above the nostrils, is not scaly, and terminates close to the caudal, its anterior

 the dorsal, and the seven anterior of the anal, are prolonged into long filaments. Pectoral 

 as long as the postorbital portion of the head. Ventrals distinct, opposite to each other. 

 Brown, with scattered, more or less irregular whitish ocelli, margined with black. Fin-rays 

 with black dots, and some entirely black for some portion of their length. On the blind

 Length of specimens, 5^ inches. Outside Nares Harbour; 152 fathoms. 



Nematops, n. gen. (Pleuronectidse). 



Cleft of the mouth narrow. Teeth minute ; scarcely any teeth on the coloured side. 

 Vomerine teeth none. The dorsal fin commences above the eye. Scales rather small,

Nematojjs microstoma, n. sj). (PI. XXIV. fig. C). 



D. 64, A. 54, L. lat. 65. The height of the body is contained twice and a half in the 

 total length (without caudal), the length of the head four times and a third. Snout 

 extremely short, with narrow mouth obliquely ascending upwards. Eyes very large, 

 two-fifths of the length of the head, very close together, the upper encroaching upon the 

 upper profile. Tentacle nearly as long as the eye, attached to its posterior half. The 

 eyes are inserted on the same level. The dorsal fin commences above the middle of the 

 eye, and terminates at a very short distance from the caudal ; its rays are of moderate 

 length. Pectorals of both sides nearly equally developed, half as long as the head. 

 Ventrals separate, opposite to each other. The scales of the coloured side are indistinctly 

 ciliated, those of the blind smooth. The curve of the lateral line is semicircular, with a 

 diameter shorter than the head. Dorsal and anal rays dotted with black, and a larger 

 black spot on the posterior dorsal and anal rajs. Caudal black, with a broad whitish
