THE TIDE-POOL FISHES OF CALIFORNIA. 
11 
The bluntuess of snout and preopercular spines, and the terminal mouth make B. recalvus easily 
distinguishable from all related forms except B. globiceps, from which it is separated by the shape and 
size of its preopercular and nasal spines, the number of its cirri, 12, and size of its mouth. The adults 
of these two species can be readily distinguished, but the young of B. recalvus is very similar to young 
of B. globiceps, indicating that B. globiceps is probably the ancestral form. Girard’s old description of 
Oligocottus globiceps has been erroneously associated with this fish, which does not extend so far north 
as the type locality of 0. globiceps. B. recalvus is distributed from San Diego to Santa Cruz, where it 
is immediately succeeded by B. globiceps on the north. No specimens of B. recalvus have been taken 
north of the region of Santa Cruz. On the other hand several specimens of B. globiceps have been 
collected on the coast of Monterey County south of Monterey Bay, therefore within the range of 
B. recalvus. The relations between the two species where their ranges overlap is still to be made out. 
B. recalvus is quite common throughout its range and everywhere inhabits deep-shaded tide-pools, 
near low-water mark, where a large number will often be found in a single pool. Here described from 
a specimen collected at Pacific Grove by Greeley & Cowles. (Type, No. fi068, L. S. Jr. Univ. Museum.)

Girard’s original description of this fish has been erroneously associated with the very closely 
related species B. recalvus, which replaces it south of Santa Cruz. />'. globiceps bryosus was based upon 
this northern form, the typical globiceps, and to it the original name is now restored. 
Head 3.66; eye 4.75; snout 3; D. ix, 16 or 17 ; A. 11 or 12; P. 13 or 14. 
Body short, stout; head deep, blunt, with a short decurved snout; interorbital space five-sixths 
of eye, deeply grooved; mouth nearly terminal and transverse, with slight lateral cleft, the maxillary 
reaching a vertical through the center of orbit; lower jaw included. Preopercular spine single, 
curved upward, nearly half diameter of orbit; nasal spines prominent, nearly half diameter of eye; 
opercle ending in a rounded flap. Dorsal fins long, slightly joined at base; no anal rays enlarged in 
male; anal papilla large. 
Cirri very numerous on top and sides of head, extending through the interorbital groove to nasal 
spines, two rows of prominent joined cirri on top of head, others between these, still others on sides 
of head; a large hunch above preopercular spine and on dorsal margin of opercle, a V-shaped row 
above pectorals, and a thick row along anterior half of lateral line. 
Color, light plumbeous brown, with traces of four or five more or less distinct black transverse 
bands, the whole body more or less vermiculated with white; some specimens largely streaked with 
white vermiculations, others nearly uniform brown; under parts dull white tinged with brown on 
under lip, and with yellow posteriorly; fins barred with yellow. The northern form of this species
