FISHES OF WEST COAST OF PERU. 127 



Galapagos Islands. A comparison of the various common names 

 with the identified specimens in our collection indicates that the 

 term " vieja negra " is applied to the black variety of .this species, 

 " vieja Colorado" to Pimelometopon darwinii; "gallo" to Bodianus 

 diplotaervlus ; " mulata " to both B. diplofaenius and P. darwinii. 



Although the only representatives of B. eclaneheri in our collection 

 are of the black variety, it is e^ddent that the name " jobero " ap- 

 plies to specimens of this species having a more brilliant coloration, 

 yellow, orange, or white and black, or combinations of these colors. 



Genus PIMELOMETOPON Gill.

Four specimens, field Nos. 09465-6 and 09678-9, respectively 25.5, 

 31.7, 25, and 32 cm. long, from Lobos de Afuera. Field Nos. .09465-6 

 were taken on the west side of westward islands. One specimen, field 

 No. 507, 26 cm. long, from Mollendo. 



The genus PimeloTnetopon is close to Trochocopus of Giinther, but 

 differs in the possession of a greater number of scales and a serrulate 

 preopercle (at least in the young), a character not noted in earlier 

 descriptions. 



Head 2.75 in length ; depth 2.98 ; eye 6.06 in head ; snout 2.34 ; inter- 

 orbital 3.5; pectoral 1.57; D. XII, 10; A. Ill, 12; scales 9-52-20. 



Body deep, compressed; head large; snout pointed, its contour 

 straight; gape of mouth extending to vertical from anterior border 

 of eye; lips fleshy, lower jaw with a flap on sides as in Bodianus^ 

 with which it agrees also in the character of the teeth; eye small, 

 about half width of interorbital ; margin of preopercle with fine 

 serrulations ; fins essentially as in Bodianus; scales smaller. 



Color in alcohol, olivaceous ; a large light olive area on side above 

 pectoral; a large black blotch covering first three dorsal spines. 

 Description based on a specimen 32 cm. long, from Lobos de Afuera.
