ment of the abdomen ; not carinated behind gastric tooth ; outline much 

 as in the preceding, as are also the eyes and antennae. Second to sixth 

 abdominal segments inclusive carinate ; telson very nearly as long as the 

 sixth segment, less deeply notched than in Pasiphcea corteziana. 



The side view strongly resembles that of 

 P. corteziana, from which the carinated ab- 

 domen and shorter carapace without median 

 carina at once distinguish it.

 which reaches half way along the eye-stalks ; the carina is a httle concave 

 at the middle of the carapace and anteriorly slopes downward, and is 

 armed with i6 small teeth or spines, two of which are on the rostrum and 

 one is terminal ; below this spine the rostrum is a compressed, finely 

 crenulate lobe. Orbital and antennal angles blunt. There is a small 

 spine just behind the orbital angle, and another still farther back in a
