SjJecies of RejJtiles and Fibjies. 423 



Misol Island. Greatest width of the disk 15 inches ; distance 

 between the front margin of the head and dorsal fin 7 3 inches. 



Scolopsis xenochrous, 

 D.^. A.f L.lat. 44. L. transv. 3|/14. 



Allied to Scolopsis glianam. 



The height of the body is coiitained thrice in the total length 

 (without caudal), the length or~ihe head thrice and a third. 

 The diameter of the eye is one third of the length of the head, 

 and a little more than that of the snout, and equal to the width 

 of the interorbital space. Infraorbital arcli with two strong 

 spines, one pointing forwards, the other backwards ; two or 

 three small denticulations below the strong spine. Preeoper- 

 culum with the angle projecting. Dorsal spines rather strong, 

 but less so than those of the anal fin ; second and third anal 

 spines nearly equal in strength and length. Brownish olive ; 

 a narrow pearl-coloured band along the uppermost dorsal series 

 of scales ; a large blackish-brown spot on the posterior part 

 of the gill-cover. A broad silvery band, three scales broad, 

 along the trunk below the lateral line ; the anterior part of the 

 band is crossed by a pair of short oblique brown streaks, the 

 middle part with a brown spot on the base of each scale ; the 

 posterior portion uniform pearl-colom*ed. Prseorbital with a 

 narrow silvery band. Fins colourless. 



Misol Island. Length 7 inches. 



Cuhiceps pauciradiatus. 

 D. 10 I 3^. A. j^. L. lat. 50. 



The height of the body is one fourth of the total length 

 (without caudal), the length of the head two sevenths. Ab- 

 domen compressed into a ridge in front of the ventral fins, 

 which are received into a groove of the posterior part of the 

 abdomen. The diameter of the eye is equal to the width of 

 the interorbital space and one third of the length of the head. 

 Snout shorter than the eye. Jaws with a series of minute 

 teeth. The vomer and tongue are armed with a long elliptical 

 patch of very small obtuse teeth ; no teeth on the palatine bones. 

 Maxillary hidden below the prjeorbital, and extending to the 

 front margin of the orbit. Humeral plate much developed, 

 triangular. Pectoral fin very long, longer than the head, and 

 extending to the vent ; not quite thrice as long as the ventrals. 

 Caudal fin forked nearly to the base ; the lobes can overlap 

 each other. Uniform brown ; inside of the mouth and gill- 

 cavity black. 



Misol Island. Length 5f inches.
