OIV THE OCCIJRREIVCE OF A .«)PE:€IG«4 OF CRElTIIVOBATEiSi AT .SAX

By ROSA SMITH. 



Three specimens of a small scaly Bleiiiiy found in those rocky tide- 

 pools which are heavily lined witli algi^e, on March (J, 1S8(). 



This Bleuny is evidently of rare occurrence, this one xjoint being at 

 present its only known habitat on the Pacific coast of the United 

 States, and these three specimens the only ones I conkl procure. It is 

 accompanied by Oligocottus analis, which in this vicinity is abundant in 

 all rock-pools, by Gibbonsia elegans of a dull color, and by Hypleurochi- 

 his (fentiUs. 



These specimens were provisionally identified as belonging to Cremno- 

 bates monophilialmus (Giinther) Steindachner {Anchcnopterns monoph- 

 thalmus Giinther, Cat. Fishes Brit. Mus., iii, 275), a species hitherto 

 known from three exam[)les from the Pacific coast of Central America. 

 My specimens differ from Giinther's description in the following partic- 

 ulars: The dorsal fin is continuous, the membrane of the third spme 

 joining the fourth near its summit in two examples, at its first third 

 in the other. The Jiead is proportionally shorter, forming two-ninths of 

 the total length instead of one-fourth, and the body is less elongate, 

 its dei^th forming one-fifth the total length instead of one-sixth. The 

 characters of the San Diegan form of this genus agree more closely 

 with Steindachner's description of Cremnobates affinis (Ichthyologische 

 Beitrage, v, 178), a species considered by its describer as doubtfully 

 distinct from G. monophthalmus. G. affinis is known from one individual 

 taken on the West Indian island of St. Thomas, the proportions and 

 coloration of which accord with my specimens, but this species also has 

 the membrane from the third dorsal spine joining the fonrtli at its base 

 ("die Membrane des dritten letzten Strahles setzt sich an die Basis des 

 foigenden ersten Stachels des zweiten Dorsales an"). 



If the specimens from San Diego j)rove to be of a distinct species, 

 which seems probable, they will be separated fj-om those already known 

 by the single merely emarginate dorsal fin, instead of two separate 

 fins. In any event, the genus Grcmnobates furnishes an interesting 

 addition to the fauna of our Pacific coast. 



Cremnobates integripinnis sp. uov. 



Description. — The body is oblong, compressed. The head is less 

 than the fourth of the total length, which measures two inches and an 

 eighth. Gape of mouth oblique, the maxillaries reaching a vertical 

 line intersecting posterior rim of orbit. Head conical, thickish, with 

 the orbits placed far forward, small fringed tentacles on their superior 

 margins, a tentacle on i)osterior margin of anterior nostril, and i)almate 

 tentacles on occiput. A cusp or spine on opercle. 



Dorsal continuous, composed wholly of spines of nearly equal height
