which are longitudinally oblong. Legs slender, edged with long, 

 fine hairs.

Material examined. — 



GALAPAGOS ISLANDS.— Albemarle Island: Reef north of 

 Tagus Hill, Tagus Cove; March 16, 1899; Stanford University; 

 1 male, 1 female, 1 young (25667). 



Eden Island, off Indefatigable Island; rock pools; April 6, 1923;

Remarks. — Very distinct from, and not to be confused with, the 

 gonagra-squamata type. In granulosa the lobes of the front and inner 

 orbit, both above and below, have smooth convex surfaces which 

 is not the case in gonagra and squamata. The granules of the gastric 

 region in granulosa are single, not combined in rows, and the arrange- 

 ment of tubercles on wrist and hand is distinctive.
