Gobius elapoides. (Plate LXIII. fig. D.) 



D. 8 1 21. A. 20. L. lat. 110. 



Body compressed, its depth being contained four times and two 

 thirds in the total length (without caudal), the length of the head 

 thrice and three fourths. Head naked, the scales from the nape 

 advancing only as far as the eye. Snout longer than the eye, 

 which is obliquely directed upwards, and nearly one fifth of the 

 length of the head. Jaws even in front ; the maxillary extends to 

 below the anterior margin of the orbit. Teeth moderately strong, 

 not quite equal in size, but none of them can be called canines. 

 The middle dorsal spines are produced ; caudal fin rounded, shorter 

 than the head. Body with seven narrow dark-brown rings edged 

 with white. The first and second correspond to the commencement 

 and end of the spinous dorsal ; the three following to the second 

 dorsal fin, on the base of which they form three ocelli ; the sixth 

 round the caudal peduncle, and the seventh on the base of the caudal 

 fin. A similar ring crosses the orbits and cheek. A straight brown 

 stripe ascends from the eye to a spot on the nape of the neck. 



One specimen, 3| inches long, has been obtained by A. Adams, 

 Esq. As it was in a bottle containing reptiles and fishes from the 

 Japanese region, it is probable that this Goby inhabits some part of 

 those coasts. 



Callionymus cookii. 



D. 4 | 8. A. 7. 



Gill- opening a small foramen on the side of the neck ; extremity 

 of the operculum produced backwards. The praeopercular spine is 

 straight, slender, considerably longer than the eye, with six or seven 

 small barbs curved upwards and inwards ; no barb at the base of the 

 spine. Head much depressed, its length being contained thrice and 

 two thirds in the total (without caudal). A longitudinal fold of the 

 skin along each lower side of the abdomen and tail. Male : — The 

 first dorsal spine and the last ray of the soft dorsal and anal pro- 

 duced. Upper parts of the body with dark transverse bands and 

 markings, the lower with small blue ocelli. The soft dorsal with 

 oblique dark bands and blue ocelli ; anal with longitudinal series of 

 blue ocelli in its basal half, and with a black spot between the ends 

 of the sixth and seventh rays ; this black spot is again ornamented 

 with blue ocelli. Caudal fin with dark cross bands, its lower half 

 ocellated with blue. 



One specimen, 3| inches long (no. 260), from the Godeffroy 

 Museum ; it was obtained at Rarotonga, Cook's Islands. 



Pat^ecus subocellatus. (Plate LXIV.) 



D. 39. A. 15. C. 10. P. 8. 



The first dorsal spine very short, the second is the longest, as long 

 as the head. The interradial membrane of the anal fin is so narrow 

 that the fin cannot be erected ; and the last ray is attached to the 

 lower edge of the tail. The three upper pectoral rays much shorter
