1143. HIPPOCAMPUS STTLIFEK, .Jordan A Gilbert. 



D. 16, covering about 4 body rings ; rings about 12 + 31. Snout not- 

 ably longer than postorbital part of head ; supraocular and temporal 

 spines long, simple; a long median spine in front of coronet; coronet 

 stout, high, its spines slender, abruptly spreading. Spines of body very 

 long and slender, each ending in a filament ; these enlarged on each 

 alternate plate of the neck, and about every fourth plate on body and 

 tail ; dorsal and upper lateral ridge usually armed and sometimes lower 

 lateral ridge ; two strong spines at base of pectoral ; body with about 50 

 developed spinous processes besides numerous smaller points. Brownish, 

 with darker bars; no pale spots; snout blackish. Coasts of Florida, in 

 deep water, known from the " Snapper Banks" off Pensacola and Tampa, 

 and from the Gulf Stream, (stylifer, bearing rods or ^jrojections.)

1144. HIPPOCAMPI'S ZOSTER.E, Jordan & Gilbert. 



Dorsal 12, on 2 -f 1 rings; rings 11 + 30. Snout very short, not more 

 than half rest of head ; supraorbital spines diverging, each with a small 

 spine before it. Coronet high, f length of snout, its filaments about as 

 long as snout. Spines on body well developed. Olive green ; sides of 

 head mottled with dusky, its margin (in <? ) broadly red. Length 2 

 inches. Pensacola Bay; the smallest known species of sea-horse, abun. 

 dant in shallow water in the lagoons, always found clinging by its tail 

 to the sea wrack, Zostera marina (whence the name zosterai).

* Hippocampus marginalUi, Heckel: 



Dorsal fin on last three of the twelve body rings. Greatest height of body eqiial to distance 

 between the coronet and the end of the snout. All the angles of the rings more developed than 

 in H. longiroslris. White spots besprinkle the head and snout, and the gill plates are crossed by 

 curved black lines; longitudinal black stripes run on the body to the seventh ring, and black 

 cross lines succeed them from the eighth to the twelfth rings; irregular interrupted black lines 

 traverse the belly lengthwise. (Kaup.) Mexico. 



t Hippocatnpus fascicularis.^ Heckel: 



Snout longer than that of //. hrevirosfri<!, with more acute nasal projections, and the dorsal 

 not standing on so high an elevation. Color black, with very many white points. Gill plates 

 striped by 10 or 11 rows of white dots, and botweeu thelateral lineaiid the rimof the belly there 

 are irregular white bands extending as far as to the seventh ring. From the eighth ring to the 

 anus there is between each pair of rings a dark cross line sprinkled with white specks, and 

 marbled. Mexico. (Kaup.)
