153. Callionymus spiniceps, sp. n. (Plate 30. fig. 4.) 



Length of head (to gill-opening) 3f in the length of the fish. Snout as long as eye, 

 the diameter of which is 3 in the length of head; eyes subcontiguous ; gill-openings 

 small, superior ; prseopercular spine straight, more than \ the length of head, with both 

 edges serrated and an outer antrorse process at the base ; maxillary not extending to 

 below the eye ; prseorbitals with serrated edges and with additional series of serrae ; 

 prsefrontals denticulated ; supraorbital ridges serrated, ending posteriorly in 2 or 3 

 spines ; occipital region rugose, with 2 pairs of spines. Lateral line single. Dorsal 

 IV, 8 ; first ray of anterior dorsal, in the male, produced into a long filament ; rays of 

 the second dorsal equal, the last reaching the caudal when laid back. Anal 8, the rays 

 increasing in length posteriorly. Pectoral reaching the fourth anal ray, ventral to the 

 second. Caudal, in the male, elongate, f as long as the fish. Head and upper part of 

 body with small dark spots. A large black spot on the upper part of the membrane 

 between the third and fourth rays of the anterior dorsal ; second dorsal with 3 or 4 

 series of oblong dark spots ; caudal with dark cross-bars ; outer half of anal blackish. 



Amirante, Seychelles Group, over 30 fathoms. 



A single specimen, 154 mm. in total length. 



154. Synchiropus sechellensis, sp. n. (Plate 30. fig 1.) 



Length of head (to gill-opening) 3^ in the length of the fish. Eyes separated by 

 a distinct interspace, their diameter 3 in the length of head; gill-openings lateral, 

 in front of the uj^per part of the base of pectoral ; prseopercular spine strongly curved 

 upwards and inwards at the tip and with two tooth-like processes on its upper edge. 

 Lateral line single. Dorsal IV, 8 ; anterior dorsal, in the male, elevated and with the 

 rays produced, but rapidly decreasing in length from the first, which is much longer 

 than the head, to the last, which scarcely reaches beyond the origin of the second dorsal 

 when laid back. Anal 7. Ventrals extending nearly to the origin of anal, pectorals a 

 little beyond. Caudal moderately elongate. Head and body with 6 broad reddish cross- 

 bars separated by irregular narrow whitish interspaces ; lower parts with white spots or 

 vermiculations. Pirst two rays of anterior dorsal and the membrane between them 

 reddish, rest of the fin dusky; second dorsal crossed by 3 or 4 oblique reddish bands and 

 spotted or vermiculated with white ; caudal with 2 reddish cross-bars ; outer \ of anal 

 blackish ; pectorals pale, ventrals pink with dusky edges. 



Seychelles Group, 37 fathoms. 



Two specimens ( d s), 55 mm. in total length. 



Allied to S. lineolatus, C. & V., differing in coloration and in the form of the 

 prseopercular spine and of the anterior dorsal fin. 



155. Synchiropus altivelis, sp. n. (Plate 30. fig. 2.) 



Length of head (to gill-opening) 3J in the length of the fish. Eyes separated by a 

 distinct interspace, their diameter 3^ in the length of head ; gill-openings lateral, in front 

 of the upper part of the base of pectoral ; praeopercular spine strongly curved upwards 

 and inwards at the tip and with two tooth-like processes on its upper edge. Lateral Hue
