560 ORDER LOPHOBRANCHII. 



The pouch for the eggs in both these groups is 

 under the tail. 



Others are destitute of anal and pectorals, but have 

 a dorsal and a caudal. They have their egg-pouch 

 under the belly \ 



Some, in fine, have no other fin than the dorsal 2 . 



Hippocampus, Cuv. (The Sea-horse.) 



Have the trunk compressed laterally, and consider- 

 ably more elevated than the tail. When curved, after 

 death, this trunk and the head have some resem- 

 blance to the bust of a horse in miniature. The 

 joinings of the scales are raised into crests, and their 

 salient angles into spines. Their tail has no fins. 



A species is found in our seas with a shorter muzzle, 

 Hipp, brevirostris, C, Will. I. xxv. f. 3 ; and another 

 with longer muzzle, Hipp, guttulatas, C, Will. I. 

 xxv. f. 5. both of which have only some filaments 

 on the muzzle and body. There are also some ap- 

 proximating species in both Indies 3 . 



New Holland produces a larger one and very re- 

 markable for the leaf-like appendages which adorn 

 divers parts of its body, Syng. foliatas, Shaw, Gen.,
