30 AnTwlida Chcetopoda 
Short antennae had appeared, the lateral being bifurcate 
at outer third. The dorsal cirrus of the next segment had 
doubled its length. 
On another specimen, there was a sudden falling off in 
width back of the 14th segment, while two other speci- 
mens had lost all save the first fourteen segments. It 
would seem that the separation of the sexual from the stem 
form takes place between the 14th and 15th segments. 
Dredged : 4 to 12 fathoms ; on shells, etc. 
PROCER-ffiA? CCERULEA 71. Sp. 
The following notes were made upon two specimens, 
taken in August, both females, badly injured, and lost by 
accident before the examination was completed. They 
belong either to Progeria or Autolytus ; their, mutilated 
condition did not admit of a positive generic reference. 
Body, strongly convex above, flat below. 
Eyes four; the anterior pair very large; the lateral, 
convex, nearly terminal; the posterior eyes, smaller, dorsal. 
Antennae : median very long, arising back of anterior 
eyes ; lateral, half as long as median, arising just in front, 
and a little outside of, anterior eyes. 
Tentacular cirri and dorsal cirri of first and second seg- 
ments, too badly injured to admit of description. Dorsal 
cirri quite long, reaching to end of the capillary setae. 
Feet same as in F. tardigrada ; first six with a fan of 
short, dark colored setae; capillary setae from the 7th to the 
2l8t segments inclusive, followed by a few segments with- 
out them. 
Color : dark blue both above and below, with perfectly 
black transverse bands, not crossing the ventral surface. 
Base of feet dark brown. Body filled with large eggs. 
Found with P. tardigrada. Dredged : 4 to 12 fathoms ; 
on shells, etc.
