runs from the carpal articulation to the base of the immovable finger ; scat- 

 tered hairs are found on the chela ; they are most numerous near the tips of 



the fingers. 



The ambulatory legs are pretty smooth, with rounded margins. The 

 dactylus of the first pair is equal to the propodite in length, while the dacty- 

 lus of the second pair exceeds the propodite. The dactyh of both pairs are 

 furnished with stiff setie, most conspicuous along the lower margin ; a curved, 

 sharp nail tips the dactyli. At the distal end of the upper margin of the 

 carpi a small, sharp tooth is seen projecting over the proximal part of the 



propodite. 



The fourtli pair of legs is sub-chelate, the rasp upon the propodite is 

 formed by a single scries of scales. The propodite of the fifth pair of legs 

 is furni.shcd with a tuft of long seta) and a broad rasp whose posterior margin 

 is concave. 



The left side of the abdomen carries three two-branched appendages. 

 The telson is divided by a broad notch into two somewhat im symmetrical 

 lobes; the posterior margin is spiniilosc. 



Length of body^ 23.5 mm. ; length of carapace^ 9 mm. 



Station 33G8. 66 fathoms. 2 males, without carcinoecia. 



These specimens agree closely with types of ^. californiensis in the U. S. 

 National Museum from Catahna Harbor, Cal., 30 to GO fathoms. 



MM. Milne Edwards and Bouvier have lately described and figured a 

 Eupagunts from Sand Key, Fla., imder the name E, smithiL'^ Since this name 

 had been previously used by Mr. Benedict for another species of Eupagunis 

 from the Gulf of California^t it becomes necessary to change the name of 

 Milne Edwards and Bouvier's species, which may be called Eupagurus houvien.
