REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



This species was described by Dr. Stimpson from specimens taken at 

 Korfolk, Va., and has since been collected by Professors Smith and Ver- 

 rill at Great Egg Harbor!, N. J., in 1^ fathoms shells and mud; by the 

 TJ. S. Fish Commission in Long Island Sound!, especially at Noank 

 Harbor !, among eel-grass {Zostera marina) and mud ; off Block Island ! 

 in 17 to 19^ fathoms sand, mud, and stones ; at Vineyard Sound !, at low 

 water and in sand, and in 1878 at Gloucester !, Mass., in mud and among 

 algae.

Paranthura Bate and Westwood. 

 Paranthura Bate aud Westwood, Brit. Sess. Crust., vol. ii, p. 163, 1866. 

 Pleon articulated, composed of six segments; thorax deeply con- 

 stricted at each end of the second segment ; antennulse and antennae 

 subequal; palpus of maxiUipeds three-jointed; inner maxillae acicular. 



The first character given above is the only one given by Bate and West- 

 wood, who, however, mention that the pleon bears the normal number 

 of pleopods ; a character that would not distinguish our species from the 

 other genera. The distinctly articulated flagellum of the antennulse is 

 j)rovided with a partial whorl of bristles, which, however, forms only the 

 most rudimentary approach toward the structure of those organs in the 

 males of the following genus. The segmentation of the pleon is indis- 

 tinct in the dorsal region, but is apparent at the sides when seen from 

 above, and the pleon does not at all resemble an additional thoracic 

 segment as in Anthura. Both pairs of antennae are provided in our 

 species with a distinctly articulated flagellum, and are of nearly equal 

 length.
