divided into two major lobes; a deep median longitudinal sulcus ex- 

 tending baclc onto the gastric region. The anterolateral margin is 

 convex, six acute teeth (more rarely seven or even eight). The first 

 pair of male appendages are well developed rods with a stout blunt 

 tip. The second pair of appendages are nearly as long as the first 

 pair, very slender, with the distal end forming one and one-half to 

 two coils of a spiral.

Type: Collected in Jamaica and originally deposited in the ''Mus. 

 Dom. Banks." 



Distribution : West Indian region ; littoral. 



Material examined : One young female. Port Antonio, Jamaica, 2 

 fms., February 17, 1926, collected by the "Ara." 



Color: Body dark wine red, the frontal margin and anterolateral 

 spines yellow ; tubercles on the upper part of the chelae violet, yellow 

 on the lower half. 



Technical description : The '' Ara" specimen is no larger than an 

 average size Pilumnus, scarcely more than a quarter of an inch wide, 

 yet it bears in miniature all the characters of the species and appar- 

 ently is the smallest egg-bearing female of the species recorded to date. 



Carapace three-fourths as long as wide, frontal region wide, four- 

 lobed, the submedian lobes being much wider than the outer pair. 

 The anterolateral margin is rounded, armed with six acute forward- 

 directed spines. The areolations of the carapace are well defined. 

 There is an irregular row of coarse tubercles on the hepatic region 

 behind the marginal anterolateral spines and running inward behind 

 the orbital region and across the gastric region, where the tubercles 

 are smaller. The postlateral half of the carapace is smooth ; the post-
