Snout whitisli, with two narrow dark bauds; opercle and lower part of 

 head with white vertical streaks. Behind the vent the dark bauds en- 

 circle the body ; before the vent the belly is immaculate. Caudal tipped 

 with black. Dorsal rays 20 ; rings 18+30. Dorsal much shorter than 

 head, on 1 + 4 rings. Head 9 in length; snout short, 2f in head; tail 

 longer than rest of body, 1^ in total length. 



Occiput crested; opercle with a cousi)icuous keel. This species is 

 very different from any other thus far found in our waters, and is an 

 interesting addition to our fauna. 



Our specimen is doubtless identical with Syngnafhus albirostris Giin- 

 ther (viii, 170) from "Mexico." The original Coryfhroichthys albirostris 

 of Kaup from Bahia and Mexico is uncertain, and must apparently have 

 been some other lish. It is said to have D. 27; rings 12+29. Syngna- 

 thuseluccns Poey is closely related, but apparently different. 



42. Hippocampus zosterae sp. iiov. P. (30852.) 



Two specimens, each less than two inches long; a male with distended 

 egg-sac, and a fenuile were taken with seiue in the Laguua Grande. 

 They were found in the sea- wrack (Zostera) in water about 3 feet deep. 



Snout very short, about 2| in head; supraorbital spines moderate, 

 diverging, each with a smaller spine in front of it. Coronet stoutish, 

 high, fully two-thirds as long as snout, ending in five small, bluutish 

 spines, besides which are a few filaments, which are about as long as 

 snout; some filaments on the back of the neck; temporal spines shaxp, 

 pouiting nearly straight out. Spine on side of throat rather short. 

 Spines on body small, subequal, sharp, straight. A spine at base of 

 pectoral, and one below it. Length of head about equal to greatest 

 depth of body. Dorsal fin covering most of two body rings and one 

 caudal ring ; the tin rather high and very short, the number of rays but 

 12. Bings 11 + 26 to 30. 



Color olive-green, the sides of the head mottled and with some paler 

 spots, especially about the eye ; dorsal mottled with dusky, in the male 

 with a broad conspicuous red margin, in life. 



The smaller number of dorsal rays seems to fully distinguish this 

 species from all others found in the Atlantic. 



43. Hippocampus stylifer sp. nov. P. (30876.) 



One specimen (9) about three inches long, "spewed up" by a Bed 

 Snapper at Pensacola. 



Snout not very short, but little shorter than rest of head, equal to dis- 

 tance from middle of eye to gill-opening; a small tubercle on the median 

 line at base of snout above ; supraocular and temporal spines long, 

 simi)le; a long spine on the median line in front of coronet, its length 

 s<;arcely less than diameter of eye; coronet stoutish, high, its five spines 

 broadly spreading, slender; the three posterior spines shortest and less 

 divergent; extent of coronet greater than its height; spines of head with 

 dermal tentacles.
