Specimens of Oligocottus maculosus from Neah Bay, Wash- 

 ington, and of Dialarchus snijderi from Pacific Grove, California, 

 occasionally have three-pointed preoperciilar spines. In some 

 cases the third spine is veiy small and appears to be an outgrowth 

 from the lower fork of the bifid spine. In others it is as well de- 

 veloped as in the typical Eximia. 



191. Blennicottus recalvus Greeley. 

 (Jordan and Evermann. 1900. IV. p. 3178.) 



Several small specimens, the longest ly^ inches in length, 

 taken by Dr. W. W. Thobnrn at the Coronado Islands. We did 

 not see it on the mainland. It is probable that the records of 

 Blennicottus globiceps this far south refer to this species, or pos- 

 sibly to Oligocottus rubeUio. The range of this species is north- 

 ward to Santa Cruz (Greeley, 1899. p. 9). It^is abundant in 

 Monterey Bay.

The type of this species, 4i/2 inches in length, was taken by 

 the U. S. S. Albatross at a depth of 45 fathoms near the Coronado 

 Islands.

Specimens from San Pedro. This species may be known at 

 once from Xeneretmus latifrons, the only other species of the 

 genus found on the south coast, by the rostral plate having three 

 upright spines. It reaches a length of 7 inches. 



In the synonomy of this species given by Jordan and Ever-
