my species to the genus Anomalocera, and make a new genus for 

 the old species. Dr. Baird^ however, thinks that the name ought 

 not to be altered; it will be necessary therefore to give a new 

 generic character. 



Genus Anomalocera. 



Antenna antica maris geniculans, tuinida. Oculi superiores quatuor. 

 Oculus inferior unicus. Pes posticus maris dexter, prehensihs. 



The four superior eyes fully distinguish it from eveiy genus 

 hitherto described. Probably in Goodsir's and Templeton^s spe- 

 cimens they were not so distinct as in Dr. Sutherland's. The 

 posterior angle of the cephalothorax on the right side is much 

 longer than that on the left. The rostrum, on the contrary, is 

 symmetrical. 



Monops agrees with Catopia, Dana, in the eyes, but that ge- 

 nus in the ' Proceedings of the Am. Ac. of Arts and Sciences ' is 

 described as follows : " Oculis superioribus nullis, inferioribus 

 grandibus, antenna maris antica dextra geniculante ; aliis Calano 



affinibus ; " in Calanus, and therefore in Catopia, the posterior 



feet are " non-prehensile, often obsolete ;" in Monops, on the con- 

 trary, they are prehensile.

Only two specimens of the above new species have as yet been 

 procured ; one was caught at Avishavelly and sent to Sir J. E. 

 Tennent, who, with his wonted kindness and liberality, trans- 

 ferred it to my collection. It lived three days with me, but re- 

 fused all food; during the day it slept, squatting on the ground, 

 with its head sunk between the shoulders ; on being alarmed it 

 sprang upwards with a sudden jerk, and after executing a rapid 

 summersault in its confined cage, it would again alight and 

 settle down like the Caprimulgi. I am informed this species is 

 not uncommon in the locality from whence it was procured.
