fig. 1. 



Carapace oblong-oval, very convex, and marked with irregular, trans- 

 verse, crenulated lines which become much less marked towards the sides 

 and posterior end. An impressed, nearly straight, transverse line behind 

 the front, and an impressed line which is concave in front on the median 

 region. Median lobe of the front subtriauguiar but rounded at the tip; 

 the lateral lobes are triangular and acute and project farther forward than 

 the median lobe from which they are separated by round, smooth sinuses. 

 Antero-lateral margins serrated. Eye-stalks long and very slender. Sec- 

 ond joint of the antenual peduncle furnished with three spines of which 

 the median is the largest and upturned at the tip; lowest spine smallest; 

 superior spine more or less upturned; flagellum very long, curved and 

 bent back under the body. Merus of the maxillipeds with the lobe at the 

 antero-internal angle rounded. First pair of thoracic legs with a strong 

 spine at the supero-distal angle of the carpus and at the infero-distal angle 

 of the propodus; dactyl ovate. Dactyls of the second and third pairs 

 falcate, very broad at the base, and subacute at the tip. Telson narrowly 

 triangular, acute; outer surface convex, smooth, glossy; margins raised 

 and furnished with two rows of hairs, the inner row lying on the surface. 



Length of carapace, 29 mm.; width, 23 mm.; length of telson, 19 mm.; 

 width of telson, 9.5 mm.; length of abdomen when extended, 37 mm. 

 The ratio of the length of the carapace to its breadth is quite variable. 



Oregon to Panama on sandy beaches. 

 Family ALBUNEID^E. 



Anterior legs more or less perfectly chelate. The maxillipeds are sub- 

 pediform or only moderately expanded, and furnished with an exoguath. 

 Telson not elongated, generally ovate and lamellate. 



Genus Blepharipoda Randall. 



Eye-peduncles very slender, elongated, cylindrical, and articulated in 

 the middle. Antennules and antennae rather long, with multiarticulate 

 flagella. Antennae devoid of an acicle. Merus of the maxillipeds narrow, 

 similar to the carpus; carpus not produced at its antero-external angle. 



Type. B. occidentalis RANDALL.
