26 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL.98 



captured 23 specimens, including the type. Until our own 28 speci- 

 mens were found sitting on the anchor chain by Lieutenant Com- 

 mander Kelly as the anchor was being hoisted prior to leaving our 

 anchorage off Tagus Cove, the species had been reported only once 

 since the Albatross collected it. Heller and Snodgrass obtained a 

 single specimen from a rocky reef north of Tagus Cove, March 3, 

 1899. 



Elizabeth Bay, Albemarle Island, Galapagos, July 26 (sta. 19- 

 38), landed in bay at south end of black beach north of mangroves, 

 north of two red islands. 



Crangon strcmius (Dana) 1 



The antennular peduncles of this one specimen are stouter than 

 what may be considered typical for the species ; the larger chela is a 

 little less massive and has its proximal portion behind the notches in 

 the dorsal and ventral margins of the hand slightly longer than usual. 

 For want of more and sufficient material, this specimen has been 

 identified as C. stromas with reservations. 



Callianidea lacvicauda occidentalis Schmitt 1 



Only the anterior portion of this specimen seems to have been 

 obtained. 



Petrolisthes species 6 



Clibanarius sp 9 



Calcinus obscurus Stimpson 6 



Leptodius cooksoni (Miers) 14J* 4$ 



Pinnaxodcs chilensis (Milne-Edwards) 1 



This is the first time this species has been observed in the Galapagos 

 Islands. Austin H. Clark, who has reported upon the echinoderms 

 collected, discovered this pea-crab in one of several sea-urchins, 

 Caenocentrotus gibbosus (L. Agassiz and Desor). 



Grapsus grapsus (Linnaeus) 1$ ovig. 



Pachy grapsus transversus (Gibbes) 1 J 1 5$ (3 ovig.)
