it is broad and pointed at its extremity and extends two-thirds the 

 length of the terminal segment. The outer branch is long and slender, 

 broad and flattened above, more rounded and 

 tapering at the extremity, somewhat incurved, 

 and extends a little beyond the end of the abdo- 

 men. Its outer edge is cren- 

 ulate and its under surface 

 armed with four spines. 



The legs are long and 

 slender, all ambulatoi^, and

Another individual was found at Catalina Island, 

 California, by Dr. J. G. Cooper. In this specimen the sixth thoracic 

 segment is also tuberculated. One specimen was 

 found by Mr. Heath at Monterey Bay on the 

 pink coralline at low tide, and is shaded with a 

 delicate pink. In this specimen, on the seventh 

 thoracic segment and the penultimate abdominal 

 segment, the tubercles on either side of the median 

 line of tubercles are single instead of double. 



Description of female. : Bod}^ oblong-ovate; 

 color, light yellow, almost white; surface of 

 abdomen tuberculated. 



Head large, much broader than long, with a 

 wide anterior margin, broadly curving on either 

 side of a small median point. Eyes small, and 

 situated at the extreme post-lateral angles of the 

 head. The first pair of antenna?, composed of 

 eight articles, reach beyond the middle of the 

 first thoracic segment. The second pair of 

 antennae, composed of twelve articles, extend to 

 the posterior angle of the first thoracic segment. 

 The first segment of the thorax is one and a 

 half times longer than any of the other segments, 

 which are about equal in length. The epimera, 

 which are distinctly marked, and roundly pro- 

 duced at their posterior angles, are much broader 

 than long.
