Lambrus hassleri, sp. nov. 
This is the Pacific coast representative of Lambrus pourtalesii Stimps. 
(L. verrilliv Smith) of the east coast of North America, It differs from the 
latter species as follows: the carapace is broader in proportion to its length ; 
the branchial regions are more expanded and inflated, the inflation extending 
farther in toward the cardiac area so as to involve the oblique row of small 
tubercles; that is to say, this row of tubercles, which in L. pourtalesii lies low 
down in the fossa between the branchial and cardiac regions, is raised up, in 
L. hassleri, on the swell of the branchial region. The spines on the edges of 
the chelipeds, moreover, are not laciniated to such a degree as in L. pourtalesii. 
Length of a female specimen, 27 mm.; breadth, including lateral teeth, 
38 mm. 
Station 3368. 66 fathoms. 1 female, 
«5 2342.77" 80 is 1 male, 1 female. 
This species was previously obtained during the voyage of the * Hassler " at 
Magdalena Bay, Lower California, August 14, 1872. The specimens then 
obtained were apparently picked up dead on the shore. 
Family CANCRIDZE. 
Xanthodes sulcatus, sp. nov. 
Carapace granulated, granulation heaviest on the lower surface, and near the 
gastric 
borders of the upper surface. Deeply impressed grooves separate the 
from the branchial regions, and the mesogastric from the lateral gastric lobes. 
The groove which continues in the median line to the front, anteriorly to the 
mesogastric lobe, is crossed a short distance behind the frontal margin by a 
transverse groove, which meets on.each side another groove running parailel to 
the upper margin of the orbit. In this way there are marked off a pair of 
frontal and a pair of orbital areolets. The frontal margin is nearly straight,
