longer and more slender than in the preceding pairs. 

 The abdomen of the female is nearly circular in outline 

 and covers the entire sternal surface. It is composed of 

 seven segments, the fourth, fifth and sixth being sub- 

 equal and larger than the others. 



Two females collected by Dr. Anderson at Santa Cruz. 



Breadth of specimen, 24 mm.; length, 20 mm. 



Breadth of specimen, 19 mm.; length, 15^ mm. 



The fingers in the specimens examined were partly 

 covered by a very short, dense pubescence. The speci- 

 mens upon which the foregoing description is based, to- 

 gether with several others described in this paper, were 

 kindly loaned to me from the collection of the California 

 Academy of Sciences by the President, Dr. Harkness. 



Cryptophrys pubescens sp. nov. 



Carapax subpentagonal, convex, the median and car- 

 diac regions tumid and separated from the hepatic and 

 branchial by a sulcus; there is a slight depression be- 

 tween the gastric and cardiac regions and another behind 

 the latter. Front slightl}^ projecting and notched in the 

 center. Antero- lateral margins not defined by a ridge; 

 the sides of the carapax are broadly rounded. Orbits 

 nearly circular; eye peduncles very short and stout. An- 

 tennules transverse ; the antennulary fossettes communi- 

 cate with each other beneath the front. Antennae shorter 

 than the width of the front. Buccal area much broader 

 than long, convex in front, concave behind. The isch- 

 ium of the maxillipeds is rudimentary ; the meros is large 

 and curved, the distal margin oblique; palp two-jointed, 

 the last joint oblong. Owing to the peculiar shape of the 

 buccal area the maxillipeds are very oblique, the distal 

 margins of the meros joints are parallel and longitudinal, 

 leaving between them a nearly square area which is filled 

 with the palpi. Chelipeds moderate, exceeding the first
