SNODGRASS AND HELLER 



Range. — Galapagos Archipelago. 



Described from 2 specimens taken at Albemarle. We have lo 

 specimens from Chatham and one from Charles. 



Orthopristis forbesi., according to Jordan and Starks and Jordan 

 and Evermann, differs from the other American species of the genus 

 principally in having smaller scales and a greater number of them — 

 80 to 95 in longitudinal series. Our specimens, how^ever, all about a 

 foot long, do not agree in this respect with the type description — the 

 number of scales varying from 66 to 78 {^6., 6'j^ 68, 70, 72, 73, 74, 

 75, 76, 78). The dorsal rays are XII, 15; XII, 16; XIII, 15; anal 

 rays III, 11 ; III, 12. 



Color in life. — Above dusky brownish; belly and sides grayish 

 with faint purplish and bluish-gi-een iridescence ; several faint dusky 

 vertical bars on sides, disappearing soon after death ; lips grayish- 

 white; membrane of spinous dorsal livid bluish, spines blue-green; 

 membrane of soft dorsal dusky ; pectoral pale dusky ; caudal dark 

 with pale border posteriorly; opercular flap dark brown; iris brown. 

 A specimen in the Stanford University collection, taken by the 

 Albatross at Albemarle, has faint spots on the membranes of the soft 

 dorsal as described by Jordan and Starks for the type. None of our 

 specimens shows these spots. 



88. ORTHOPRISTIS LETHOPRISTIS Jordan & Fesler. 



Orthopristis lethopristis Jordan & P^esler, Proc. Acad. Nat. Sci. Phila. 1889, 

 36, Galapagos Islands. — Jordan & Evermann, Fishes North and IMid. 

 Amer., 11, 1340, 1898. 



Range. — Galapagos Archipelago. 



Heretofore only the type of this species known. We have 4 speci- 

 mens, the longest 330 mm. in length, from Tagus Cove, Albemarle, 

 and Duncan. 



All of our specimens have a slight serration on the bony posterior 

 margin of the preopercle, being not " strictly entire" as described by 

 Jordan and Evermann. Each has a wide band of scales on the mem- 

 brane of the soft dorsal and of the anal back of each ray reaching to 

 the margin of the fin.
