aud more distinct posteriori j- ; 2 pinkish spots on the dorsal side of the 
caudal peduncle, and a faint shading of the same color on side of head 
and along anterior fourth of lateral line; entire iiuder surface dull brown, 
tinged with olive ; tins indistinctly barred with grayish white ; tail faintly 
tinged with pink. In some specimens the color is an almost uniform dull 
brown while in others the light markings are prominent. Some young: 
individuals from among the green algae are uniform light green. 
The bluntness of the snout and preopercular spines, and the terminal 
mouth make this species easily distinguishable from all related forms, 
except B. (jJoMceps, from which it is separated by the shape and size of its 
preopercular and nasal spines, the number of its cirri, 12, and the size of 
its mouth. The adults of these 2 si)ecies can be readily distinguished, but 
the young of B. recahnis is very similar to the young of B. (jlohiceps, indi- 
cating that B. gloiiceps is probably the ancestral form. Girard’s old descrip- 
tion of Oligocottus cjloMceps has been erroneously associated with this tish, 
which does not extend so far north as the type locality of B. glol)iceps. B, 
reccdvns is distributed from San Diego to Santa Cruz, where it is immedi- 
ately succeeded by B. glohiceps on the north. No specimens of B. recahnis 
have been taken north of the region of Santa Cruz. On the other hand, 
several specimens of B. gJobiceps have been collected on the coast of Mon- 
terey County south of Monterey Bay, therefore within the range of B. 
recalvus. The relations between the two species where their ranges over- 
lap is still to be made out. B. recalvus is quite common throughout its 
range and everywhere inhabits the deep shaded tide-pools, near low water 
mark, where a large number will often be found in a single pool. (Greeley.)

This genus is allied to Oxycoitus, differing in the presence of minute 
prickly scales, which cover dorsal half of body. Preopercular spine sim- 
ple, sharp. No slit behind the last gill, (ruscum, the butcher’s broom, a 
rough-skinned plant.)
