under capitulum bright orange all around. Sack internally 

 dark purplish lead-color. Body and cirri nearly white or pale, 

 purplish lead-color, with arms of second, third and fourth cirri, 

 and pedicels of fifth and sixth, more or less tinted orange. Fresh 

 ova peach-blossom red, immature ova, in ovarian tubes, pale 

 pink. Capitulum one and one-half inches. (Darwin.) 



Remarks. — Common on ships' bottoms from tropical seas, and 

 distributed world-wide. Also often attached to fuci, pumice, 

 Janthinae, Spirulae, etc. It is often associated with Lepas 

 anatifcra and Lepas hillii, and in a young state with Lepas 

 fasicularis, according to Darwin. It has been found at Asbury 

 Park, according to Pilsbry.

Description. — Capitulum variable in length compared with 

 breadth, chiefly due to greater or less production of occludent 

 portion of terga. Valves thin, brittle, variable furrowed sur- 

 face narrow and broad ridges often alternating. Frequently 

 each ridge, especially one extending from umbo to apex of each 

 scutum, sometimes that alone, covered with prominent curled 

 flat calcareous spines, or these sometimes absent. From thin- 

 ness of valves and depths of furrows, edges of valves sinuous. 

 Ridge extending from umbo to apex of scuta unusually promi- 

 nent and curved, runs very close to occludent edge, so that only 

 very narrow space left between this edge and ridge. Internal
