THE FOSSIL STALK-EYED CRUSTACEA 127 



is the attachment of seemingly two large spines. The surface is not 

 entirely granulate; through the middle there is a broad longitudinal 

 smooth band, and a little above this and separated from it by a 

 roucrh line of granules, there is another but narrower smooth strip; 

 the ''extreme upper part of the outer surface is smooth; the granules 

 of the lower half are mostly fine. An indication of a spine on lower 

 margin a little distad to the middle. 



The carpus or wrist is very incomplete as to the distal end, the 

 extreme length visible is 5.2 mm., the width 4 mm. Surface very 

 convex transversely, upper half granulate, also distal end of lower 

 half- lower proximal portion smooth, with a dimple near the arti- 

 culation with the merus; the upper distal half is much more produced 

 than the lower half, as in B. occidentalis. 



The fourth fragment appears to be the upper part of a manus, 

 with the condyle at the articulation with the dactylus; surface very 

 uneven and finely granulate. 



Occurrence.— W^sYimgion: Sea cliffs between Classens Wharf and 

 ship canal estuary, Townsend Bay; lower Oligocene series; two 

 specimens, one containing a right manus, holotype, and what ap- 

 pears to be the left merus of the cheliped, outer-upper face, and the 

 other containing a left carpus and a fragment which may be part of 

 a manus. Holotype in Stanford University. 



Relation.— Th.\Q can not be referred to the Kecent B. occidentalis 

 because in the latter the lower edge of the palm is thinner and 

 sharper and the granules of the outer surface form longer lines which 

 are arranged more or less in parallel rows.

Family ERYMAIDAE Van Straelen, 1925 ^^ 



Carapace subcylindrical, rostrate, having always a well-developed 

 cervical suture and postcervical and branchio-cardiac sutures. An- 

 tennules biflagellate. Antennae with a long flagellum and a scapho-

 Rostrum medium; cervical suture deep; branchio-cardiac and post- 

 <»ervical sutures nearly parallel; hepatic sutures almost encircling a 

 tubercle formed between these sutures, the cervical and the antennal 

 sutures; on median line in front of cervical suture a fusiform area 

 limited by two furrows; the antennular flag ella inserted on a short
