LAOPHONTE TALIPES, new species 



PluVTE 14 



Oecui^'ence. — Fifty specimens, including both sexes and females 

 with ovisacs, were washed from the sand on the shore of the French 

 Watering Place on Naushon Island, August, 1927 ; a single male and 

 female were washed from the sand on the surf beach of the southern 

 shore of Marthas Vineyard, August, 1927. A male with a female in 

 copula is taken as the type of the species, U.S.N.M. No. 63433 ; female , 

 paratype, U.S.N.M. No. 60425. 



Color. — Body transparent with a pinkish or reddish tinge, the 

 male often bluish ; eggs pale blue ; eye dark red. 



FeTiiale. — Body slender and tapered regularly backward, with no 

 sharp distinction between metasome and urosome; cephalic segment 

 as wide as long; rostrum short and bluntly rounded with a seta on 

 each side at the tip. Epimeral plates quite prominent at the pos- 

 terior corners of the thoracic segments; genital segment distinctly 

 divided in the middle; anal segment much longer than the penulti- 

 mate segment; caudal rami twice as long as wide and somewhat di- 

 vergent, the terminal seta half the body length. First antennae 

 6-segmented, two-thirds as long as the cephalic segment, and rather 

 stout ; the third segment has three long setae in a transverse row on 

 its dorsal surface, the fourth segment is one-half longer than the 

 third and carries a slender aesthetask, the fifth segment is very 

 short and is the only one not well armed with setae. The two endo- 

 pod segments of the second antenna are the same length; the distal 

 segment has four apical setae, the two middle ones geniculate, and 

 a row of slender spines on its inner margin, increasing in length 

 and thickness distally. The basal segment is much stouter, with a 

 fringe of hairs and one seta on its inner margin and a spine at the
