138 LOPHOBEAXCHII. 



rayed, very long, extending beyond the origin of the anal, coalesced with its inner side 

 to the integuments of the body, both ventrals forming the egg-sac. 



Ground-colour generally brown, minutely dotted with black and whitish. Dorsal 

 fin with a large bluish-black ocellus between the first and second and second and third 

 rays ; the top of the fin of a beautiful purplish red, the remainder marbled like the 

 body. Caudal with numerous small, oval, purple spots and dots. 



In a second variety the markings are the same ; but the ground-colour is rosy, and the 

 markings are purplish brown. 



Length from 4 to 5 inches. 



Zanzibar. East-Indian archipelago. 



Kaup {Cat. Lqph. Fish. p. 2) states that in the males of S. paradoxum the egg-pouch 

 is formed by the union of the inner edge of the ventrals to the skin of the belly, and 

 that in the females the ventrals are free as in other fish. All the specimens from 

 Zanzibar which have been examined have the ventrals attached to the skin of the 

 belly, and all of them axe females; so that if the first part of Kaup's remarks proves 

 to be true, both sexes in this species cany eggs. 



We may state that we have ascertained by dissection that specimens having eggs in 

 the ventral pouch have at the same time ova in the ovaries scarcely less developed than 

 those in the pouch.

 Cataphractus draco, Gronov. Syst. ed. Gray, p. 144. 



There are two specimens in this collection. The larger one is 2-5 inches long; and 

 the projecting part of its snout, measured from the anterior rim of the orbit, is 0-3 inch ; 

 it is considerably dilated on its lower surface, forming an oval disk. The second 

 specimen is 1*9 inch long; and the projecting part of the snout is - 25 inch, conse- 

 quently comparatively much longer than in the other ; it is also much narrower, the 

 projecting part being tetrahedral, with the sides equal and the edges strongly serrated. 

 In other respects the specimens are alike. 



Zanzibar. East-Indian seas. 



HIPPOCAMPUS, Cuv. 



473. Hippocampus mannulus. 

 Hippocampus mannulus, Cant. Mai. Fish. p. 388, pi. 11. f. 1. 



This specimen appears to be H. mannulus, a species which apparently is distinguished 

 by the frontal crest not terminating in a spinous projection in front. 

 Zanzibar. Pinang.
