of first cirrus and one on flanks of prosoma. Mouth with 

 palps accuminated. Mandibles with five teeth, first not far 

 remote from second, and inferior point rather broad and 

 finely pectinated. Maxillae with two large unequal upper 

 spines and four regular steps. Posterior cirri with upper 

 parts of segments slightly protuberant. Young with spines 

 of five pairs in two converging lines in upper half of each 

 segment, with numerous minute lateral marginal and interme- 

 diate little bristles. Large examples with all latter so increased 

 that noniial five pair indistinguishable, and front of each seg- 

 ment covered by triangular thick brush of bristles, all pointing 

 in same direction. Dorsal tuft on each segment of six or seven 

 large spines with one to three dozen fine ones. First cirrus and 

 anterior ramus of second cirrus with broad brushes and bristles. 

 Pedicels of all cirri thickly covered with bristles. Caudal ap- 

 pendages smooth, with rounded summits. 



Color in alcohol with front surfaces of segments of cirri and 

 of pedicels purple. Sometimes parts of sack and interspaces be- 

 tween two scuta fine purple. Shell and body said to be pale blue, 

 and cirri spotted with brown, when fresh. Length of capitulum, 

 1.6 inches; breadth, 1.2. (Darwin.) 



Remarks. — Recorded from Beach Haven by Leidy, in 1888, 

 who found it feeding on Cyclops. I have examined examples 

 from Cape May and Atlantic City, the latter obtained by the late 

 John Ford. Mr. Witmer Stone obtained it at Point Pleasant. 



Widely distributed in most seas. Darwin says it occurs at- 

 tached to fuci, Spirul?e, Janthinse, Velellas, and often to feathers 

 and cork. He also says it is often associated with the young of 

 Lepas anserifera (var. dUatata), and Lepas pectinata. The 

 yellowish ball, noted above in the description, is said to serve as a 

 buoy to float the animals.
