Miss H. Ricliardson on the Isopods of the 



three new species agree with the generic characters of Giliccea 

 except in the presence of the spine, we consider them for the 

 present new and undescribed species of Giliccea.

Cilicaa cordata. x 8. 

 a, tead and first thoracic segment ; b, dorsal view. 



shaped. Frontal margin broadly lobed on either side of 

 median point. Eye situated at post-lateral angle of head. 

 First pair of antennae reach beyond the posterior margin of 

 head ; first joint of peduncle oblong ; second joint very short ; 

 flagellum contains about nine articles. The second pair of 

 antennge extend to the posterior angle of the third thoracic 

 segment ; the flagellum contains about fifteen articles. 



The thoracic segments are about equal in length, with the 

 exception of the first, which is a little longer than any of the 

 others. The epimera are very broad and drawn out to an 

 apex, which is rounded. They are scarcely visible in a 

 dorsal view, as they project downward laterally, forming an 

 angle with the segments. The last thoracic segment is 

 furnished with low tubercles on its posterior margin. 



On the first abdominal segment are five double tubercles.
