486 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
agrees with Peters’s description, the dorsal rays being x11, 15, not 
xvul-I, 15, as stated by Peters. This species is probably the one 
poorly described by 'I'schudi under the name of Pristipoma scapulare. 
It is well distinguished by the color mark, which has suggested the 
names scapularis, melanospilus, and notatus. 
57. ANISOTREMUS DAVIDSONI. 
Pristipoma davidsoni Steind., Ichthyol. Beitriige, m1, 6, 1875 (San Diego); Jordan & 
Gilbert, Proc. U.S. N. M. 1881, 585 (Catalina Island, San Diego). 
Habitat: Coast of southern California. 
Etymology: Named for Prof. George Davidson, of San Francisco. 
This well-defined species is not rare about San Diego and neighbor- 
ing islands. It has not been taken elsewhere. 
58. ANISOTREMUS TA:NIATUS. 
Anisotremus taniatus Gill, Proc. U. 8. N. M. 1861, 107 (Panama). 
Habitat: The Pacific coast of tropical America, Magdalena Bay to 
Panama. 
Etymology: tawéa, a ribbon; teniatus, striped. 
This species, the most brilliantly colored of the genus, is common 
on the Pacific coast of tropical America, where it replaces the closely 
allied Anisotremus virginicus. The differences between the two species, 
though slight, seem to be constant. Steindachner records the species 
from Magdalena Bay. Our specimens are from Mazatlan and Panama.

Pristipoma acara pinima Castelnau, Anim. Nouy. ou Rares, 1856, 8. 
Habitat: West Indies, Florida Keys to Brazil. 
Etymology: Virginia, but the species does not reach thus far to the 
northward. 
This well-known species is the commonest of the genus in the West 
Indies and is the only one which extends its range to the coast of 
Florida.
