Neanthias accraensis, Norman. 



193 1, Ann. Mag. Nat. Hist. (10) vii, p. 354, fig. 2. 



St. 279. 10. viii. 27. Off Cape Lopez, French Congo. Large otter trawl, 58-67 m.: i specimen, 

 130 mm. 



This species was known previously only from the Gold Coast. In life the belly is 

 said to be silvery and the upper part of the body darker. The head is ornamented with 

 3 or 4 broad oblique yellow bands. The median fins are mottled with yellow, and the 

 soft dorsal is fringed with red. 



Rhegma guineensis, sp.n. 



St. 283. 13. viii. 27. Off Annobon, Gulf of Guinea. Large dredge, 18-20 m.: i specimen, 29 mm. 



Very close to R. thaimoshim, Gilbert, from the Pacific coast of Panama, but without 

 supraocular tentacles. Depth of body about 3 i in the length, length of head 2\. Snout 

 shorter than eye, diameter of which is 4 in length of head and more than twice the

interorbital width. Maxillary extending to a very little beyond posterior margin of 

 eye; lower jaw a little projecting; no distinct canine teeth in jaws, but some of the 

 anterior teeth apparently somewhat enlarged. A single broad spine on the praeoper- 

 culum; two broad, flat spines embedded in the operculum. About 5 gill-rakers on 

 lower part of anterior arch. 48 (?) scales in lateral line. Dorsal VII 20. Anal III 16 

 or 17. Pectoral extending nearly to above first anal spine, a little shorter than head. 

 Brownish above, rather paler below ; a round dark spot, a little smaller than the eye, 

 on the operculum ; sides of head with traces of two dark lines ; dorsal, anal and caudal 

 fins blackish ; other fins paler. 



One other species of this genus has been described, namely Caribrhegma gregoryi, 

 Breder, from the Glover Reef off the coast of British Honduras. In this species supra- 

 ocular tentacles are present, and the dorsal has 15 soft-rays, the anal 12. The two flat 

 spines on the operculum said to be characteristic of Caribrhegma are to be found also 

 in Rhegma thaumasium, and the other differences mentioned by Breder seem to be 

 only of specific importance. 



1 The course of the lateral line shown in the figure is doubtful, as most of the scales are missing in this 

 region.
