TORRE 
POLYCHELES GRANULATUS. 123 
What I have here considered to be the rudiments of epipods on the tenth 
to the thirteenth pairs of appendages are simply thin membranous expan- 
sions at the base of the podobranchiz similar to those of P. xanus. The 
third maxilliped carries a minute epipod but no podobranchia. Connected 
with the articular membrane at the base of this appendage is a single minute 
arthrobranchia. This is present in the typical P. scudptus also, in which it 
has been interpreted by Smith as a questionable podobranchia.* 
Dimensions of a female: length, 110 mm.; length of carapace, 48 mm. ; 
breadth of carapace, 35 mm.; length of antennal scale, 10 mm.; length of 
telson, 20 mm.; length of cheliped, 123 mm. (ischium, 21 mm., merus, 
36 mm., carpus, 25 mm., propodite, 39 mm., dactylus, 24 mm.). 
A sketch of a living specimen (Sta. 3553, 695 fath.), made by Mr. 
Westergren, and reproduced on Plate C, shows the color to be a pale rose 
purple on the dorsal side of the carapace and abdomen, deepening to a 
brighter orange red on the thoracic appendages, the branches of the pos- 
terior abdominal appendages, and the flagella of both pairs of antenne, 
and fading to a delicate bluish white on the hepatic and anterior branchial 
regions. The raised ridges of the carapace and abdomen are whitish, the 
sete on the margins of the basal parts of the antennz, swimmerets, etc., are 
yellow. Some of the depressed areas of the hinder portion of the carapace 
and abdomen display a greenish tint in the colored drawing, but I suspect 
that this hue was derived from a little of the adhesive green mud which 
formed the bottom from which the specimen came.

Carapace long oval, its greatest width at the anterior branchial region ; 
the dorsal surface of the carapace is furnished with microscopic sete and is 
granulated but almost destitute of spines ; there are two small rostral spines, 
and back of these, on the low granulated median carina, lie four spinules 
arranged in two pairs, the posterior pair closely followed by a single spinule ; 
all of these spinules are on the anterior half of the gastric area ; the sub- 
marginal ridge on the branchial regions is incurved and composed of minute 
spinulose granules ; the hepatic region is but indistinctly separated from the
