﻿COPEPOD GENUS PUPULINA (CALIGOIDA) — WILSON 255 



and TeeVan ; off Santa Catalina Island, Calif. ; October 3, 1946. 



Three females, two ovigerous ; three males ; collected by Ruby Bere, 

 "around the mouth of a devilfish (probably Mohula hypostonia) ^^'' 

 Lemon Bay, Fla., Gulf of Mexico. Identified and reported as Pwpu- 

 lina flores by Bere (1936) . 



Types. — Holotype female, U.S.N.M. No. 85973; allotype male, 

 U.S.N.M. No. 85972; Gulf of Mexico specimens. 



Diagnosis. — Length of anterior and posterior parts of body ap- 

 proximately equal in both sexes. Processes of genital segment of 

 female reaching to near the middle of the abdomen. Caudal rami 

 linear and a little longer than abdomen in both sexes, attached later- 

 ally, divergent in female. Outer piece of first maxilla not produced 

 distally in female, only slightly so in male; inner piece in male with 

 small spine near distal outer margin. Male maxilliped \\\t\\ process 

 of basal segment elongated. Posterior ventral accessory processes 

 with small lobed membranous extension distally. Leg -i with inside 

 spine on segment 3, cuticular process on segment 4. 



Description. — Femai^ (pi. 13, fig. 1) : Gulf of Mexico specimens: 

 Total length, (>. 8-7.0 mm.; average length and width of carapace, 3.2 

 nnn. California specimens : Total length 5.9 mm. ; length and width 

 of carapace, 2.5 mm. 



Anterior and posterior margins of carapace curved; sides slightly 

 rounded. Median sinus a small rounded pit ; posterior sinuses rather 

 shallow. Distal edges of lateral area set thickly with long hairs, edge 

 of thoracic area with a few spinules. Main lines of dorsal grooving 

 well defined, that of central cephalic area not distinct in available 

 specimens. 



Free thoracic segment almost three times as wide as long ; posterior 

 margin set with very minute spinules. Genital segment two-thirds 

 wider than long at middorsal line; sides tapering gradually, armed 

 marginally with short spinules. Processes with rounded points, ex- 

 tending nearly to the middle of the abdomen; inside, the processes 

 not arising on either side of the base of the abdomen as in P. flores^ 

 the posterior margin of the genital segment being extended beyond 

 this point. Design on dorsal surface of genital segment with rounded 

 peak at top, and single lobes at side and bottom ; this pattern identical 

 in the two lots of specimens. Ovisacs reaching slightly beyond end 

 of caudal rami in all specimens. 



Abdomen slender, indistinctly 3-segmented; a dorsal inflation of 

 the anterior portion of the proximal part the only indication of its 

 division into two joints; this basal portion almost twice the length 

 of the anal segment; both set with marginal spinules, dorsal surface 

 with long slender hairs. Caudal rami slender, a little longer than 

 abdomen ; attached to the anal segment laterally, and divergent from
