2G2 On Deep-sea Fishes from the Sea of Oman. 



Pakascolopsis, gen. nov. 



Agrees in every respect with Scolopsis, Cuv., but tor the 

 total absence of a suborbital spine. iScoIopsis inermis, Sclileg., 

 in which the said spine is feeble, is a link between the two 

 genera. 



5. Parascolopsis Totonsendi, sp. n, (PI. VI.) 



Depth of body equal to length of head, 2f to 2| times in 

 total length. Snout very short, shorter than the eye, the 

 diameter of which is 3 to S^ times in length of head ; inter- 

 orbital region flat, equal to the diameter of the eye ; nasal 

 openings large, separated by a dermal flap; mouth with 

 bands of small conical teeth, outer largest; maxillary ex- 

 tending to below anterior third of eye ; suborbital and prse- 

 opercular borders finely denticulated ; a single well-developed 

 opercular spine ; head entirely covered with strongly ctenoid 

 scales. Gill-rakers very short, tubercular, 6 or 7 on lower 

 part of anterior arch. Branchiostegal rays 5. Dorsal 

 X 8-9 ; spines strong, middle longest, f or nearly ^ length 

 of head, as long as longest soft rays. Anal III 7 ; spines 

 strong, second and third equal and nearly ^ length of head. 

 Pectoral acutely pointed, | or f length of head. Ventrals 

 extending to vent. Caudal deeply notched. Caudal peduncle 

 nearly twice as long as deep. Scales strongly ctenoid, 

 45_4.y t=^' lat. 1. 37-42. Uniform reddish, with a more or 



less distinct silvery lateral stripe. 



Several specimens, measuring from 110 to 160 millim., 

 were obtained at three different points : — 



Lat. 24° 5' N., long. 57° 35' E., 205 fathoms. 



Lat. 25° 22' N., long. 57° 47' E., 225 fathoms. 



Lat. 25° 31' N., long. 57° 14' E., 198 fathoms. 



6. Tetraroge Ouentheri, Blgr. 



Two specimens. 



Lat. 23° 56' N., long. 58° 5' E., 142 fathoms. 



This species was described from a single specimen obtained 

 at Muscat by Surgeon-Lieut.-Col. A. S. G. Jayakar. The 

 present specimens differ from the type only in having 12 soft 

 rays to the dorsal instead of 11. 



7. Fhysiculus argyropastus^ Alcock. 



Several specimens. 



Lat. 24° 5' N., long. 57° 35' E., 205 fathoms.
