every medium low tide. Plocamium, coralline, and other alge, as well 
as Zostera, were growing on sides and bottom of the pool. Total length, 
24 inches. 
A specimen, larger (24 inches total length) than either of the type 
specimens, was collected at the first-known habitat on the 17th instant. 
It was in a large, deep pool, where the water was frequently changed 
by the breaking of the surf, under a heavy growth of “ eel-grass” and 
sea-weeds. In addition to the species first found in company with 
Cremnobates, an adult example of Heterostichus rostratus (GQrd.) was 
taken. This fine specimen of Cremnobates was brought a distance of 
12 miles in about a pint of sea water, and lived 28 hours after it was 
captured.

NOTE ON THE OCCURRENCE OF GASTEROSTEUS WILLIAMSONE 
GRD., IN AN ARTESIAN WELL AT SAN BERNARDINO, CAL. 
By ROSA SMITH. 
Length, 13 inches to base of caudal. Head, 24 in length; depth, 34; 
eye, 3 in head. 
Dorsal spines rather short; very slightly serrate; ventral spines 
reaching tip of pubic bone, serrate on both edges. The single specimen 
is so badly dried and decayed as to render it impossible to count the 
soft rays of any of the fins except the pectoral; the caudal fin is mostly 
broken off, and the anal spine is not discernible; the second dorsal 
spine has come off and the third is very small. Pectoral rounded, of 
10 rays. The color is, of course, dark brown from drying. Some dark 
punctulations are seen, with a magnifying glass, on anterior part of 
body. ‘Top of head, scapula, and suborbital bones, granulate; opercles, 
striate. The pubic process, extending upward from ventral to middle 
of the side, is perpendicularly striate. 
After having become thoroughly dried the specimen was given to Mr. 
W. G. Wright, of San Bernardino, who preserved it in spirits. It is 
said to have emerged from the pipe of an artesian well from a depth of 
191 feet. Mr. Wright informs me that the pipe is so situated as to make 
it impossible for any one to have placed the fish in the pipe, as, after 
rising from the well 9 feet from the ground surface, the pipe is returned 
underground and runs horizontally a distance of 50 feet and then feeds 
a tank inside a building, the supposition being that the fish found its 
way into the well from some subterranean stream. 
The specimen has been presented to the United States National Mu- 
seum. 
The species is evidently a true Gasterosteus and not an “Hucalia.” 
It is closely related to G. microcephalus, but lacks the lateral plates of 
that species.
