X. Description of a New Genus of Perciform Fishes from the Cape of 

 Good Hope. By G. A. BOULENGEK, F.R.S. 



(With Plate IX.) 



ATYPOSOMA, g. n. 



BODY compressed ; scales small, finely ciliated ; lateral line 

 complete. Mouth large, moderately protractile ; maxillary large, 

 exposed ; jaws equal, with a band of small villiform teeth ; preopercle 

 very finely serrated ; no opercular spine. Gill-membranes separate ; 

 seven branchiostegals ; gill-rakers very long. A single dorsal, with 

 11 spines and 17 soft rays, the spinous portion well developed, but 

 shorter than the soft ; anal with 3 spines and 14 soft rays ; soft 

 dorsal and anal thickly covered with small scales. Caudal forked. 

 Pectoral with 17 rays, asymmetrical, rounded, upper rays longest. 

 Ventrals behind base of pectorals, close together, with a strong spine. 

 This genus, referable to the Scorpidine Squamipinnes, is nearest 

 allied to Atypichtliys, Gunther, from which it is distinguished by the 

 large mouth and large maxillary. I regret to be unable to say 

 anything of the palatal dentition, the palate being absent in the 

 stuffed specimen. 



ATYPOSOMA GURNEYI, sp. n. 



Depth of body 2^ times in total length, length of head 3. 

 Diameter of eye 5 times in length of head, 1^ in interorbital width ; 

 maxillary scaly, extending to below anterior third of eye, the 

 diameter of its distal extremity f that of eye ; preopercular border 

 forming a right angle, rounded and very finely serrated at the 

 angle ; head nearly entirely covered with very small scales. Dorsal 

 xi 17, originating above base of ventral ; spines rather strong, 3rd
