is characteristic of the genus C'diaca. It lias been noted by Stebbinj?,' 

 by Miers,^ and by Ilaswell ' that with many siwcios of CUiava, as well 

 as with some of the other f^enera of the kSplia-romidic, the spine is pres- 

 ent and develoi)ed in the males but wanting in the females. As our 

 three new species agree with the generic chara(;ters of Cillcna except 

 in the preseiK^e of the spines, we consider them for the present new and 

 undescribed species of Ciliava. 



31. CILICiEA CORDATA, new species. 



Body attenuated in front; color a faint yellow, profusely marked 

 with a delicate pink tint. 



Head with the anterior margin thickened, and slightly juoduccd 

 in front. Prominent median point triangularly shaped. Frontal mar- 

 gin broadly lobed on either side of median 

 point. Eye situated at post-lateral angle 

 of head. First pair of anteniuc reach 

 beyond the posterior margin of head; first 

 joint of peduncle oblong; second joint very 

 short; llagellum (contains about nine arti- 

 cles. The second pair of anteniiii' extend 

 to the posterior angle of the third thora(;ic 

 segment; the Hagellum 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, form- 

 ing 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. The terminal segment 

 of the body has three sinuses, one above 

 another, the two upper openings being 

 heart-shaped. Six teeth are grouped in a 

 series of two each, and are placed in such 

 regularity as to give the ajjpearance of a triple sinus. At the base of 

 the ui)per sinus is a large rounded tubercle, peaked at the top. Three 

 double tubercles are also situated at the base of the abdomen. The inner 

 branch of the uropoda is fixed and immovable; it is broad and pointed
