210 BULLETIN OF THE 
segments are smooth, the impressed lines are absent with the exception of the 
hinder one of the deeply cut pair, and the pleure are broadly rounded below ; 
the peduncle of the second antenna is not much over one half the length of 
the antennal scale, and the whole appendage is but little longer than the 
carapace.

The color in life, as shown in a sketch made by Mr. Westergren, is light 
greenish yellow, banded with vermilion on the branchial regions and abdomen. 
Appendages red, antennary flagellum transversely banded with light and dark. 
The coloration is quite different from that of S. edwardsii as given by Dana 
(Crust. U. S. Explor. Exped., p. 602). 
Sicyonia picta, sp. nov. 
Rostrum a little shorter than the eyestalks, laterally compressed, elevated, 
armed with six teeth, three superior, three terminal; inferior margin ciliated. 
Carapace carinate in the median dorsal line; the carina is furnished with two 
teeth, one minute, on the anterior part of the gastric region at the base of the 
rostrum, the other larger, over the cardiac region. An infra-orbital and an 
hepatic spine are present. General surface of carapace punctate and sparsely 
clothed with sete. Abdominal segments smooth, with a median dorsal carina 
which rises into a strong tooth on the first segment directed upward and 
forward ; on the fifth and sixth segments the carina is drawn out into an acute 
tooth which is directed horizontally backward. The pleurz of the abdominal 
segments are margined and armed with a tooth on the lower border; on the 
second, third, and fourth segments the tooth is hamate, being directed out- 
ward and backward. The general surface of the abdomen is smooth, with a 
transverse groove on each side of the segments. The telson is channelled 
above, acute at the tip, and armed with a pair of small lateral spines near the 
distal end. The eyes are very large, horizontally flattened. Basal segment of 
antennule armed with two spines on its exterior border; flagella shorter than 
the peduncle. The peduncle of the second antenna reaches about two thirds 
of the way to the end of the scale; the flagellum is about equal to the abdo- 
men in length ; the basal segment of the peduncle is furnished with a long and 
acute external spine. The sternum is armed with a long spine between the 
bases of the second, third, and fourth pairs of legs, as is usual in species of this 
genus. The last pair of abdominal appendages are a little shorter than the 
telson.
