506. Storer on the 
S. Peckianus. Nobis. Peck’s Pipe Fish. 
so Plate I. Fig. 2. 
The specimen here described was received from 
Dr. Yale, who thus writes me from Holmes Hole: 
“The small pipe fish was taken in a pond, south 
side of the Island, which communicates with the 
sea.” 
- Its length is six inches. Its whole surface is cov- 
ered with horny striated plates; the body gradually 
tapering from the head to the tail, at which part it is 
nearly a point. On each side of the anterior portion 
of the body, are three ridges, and one passes from 
the neck through the middle of the abdomen to the 
vent; this ridge upon the abdomen does not exist 
back of the vent. In front of the posterior extremity 
of the dorsal fin, the body is hexangular ; back of 
this fin, quadrangular. Color of the specimen very 
similar to that of the preceding species. The divis- 
ions of the abdominal plates marked on their outer 
edges by lines of a darker color; these are very ob- 
vious upon the plates of the posterior portion of the 
body ; much less distinct upon the plates in front of 
the dorsal fin. Length of the head, from the ex 
tremity of the snout to the posterior angle of the 
operculum, nearly six lines; a depression between 
the eyes; and aridge upon the occiput, which ig 
continued on to the neck. Operculum pectinated ; 
or, appearing to the eye of a conchologist of the form 
of a Pinna; small at the anterior inferior portion ; 
quite broad at the posterior, rounded beneath and 
behind, and covered with stri: radiating from its cir-
