eggs were salmon colored." Bere (1936) referred to the "smaller 

 females" (Gulf of Mexico specimens) which are here designated as 

 belonging to this species, as having the carapace "creamy with much 

 branched reddish purple pigment spots; genital segment and egg 

 strings rose colored ; eyes black." 



Reinarhs. — The only noticeable differences between the Gulf of 

 Mexico specimens and those from the Pacific are in the larger size 

 of the former and in the thicker integument of the latter. 



It is interesting to note that this species occurred in both collections 

 with another species of the genus, in the Gulf of Mexico with Pupulina 

 flores and in the Pacific with the other new species herein described. 



The name minor refers to the notably small size of this species, com- 

 pared with that of the other known species. 



PUPULINA BREVICAUDA, new species 

 Plate 14, Figures 1-7 ; Plate 15 



Specimens examined. — Eight females, 2 adult, nonovigerous, others 

 in various development stages; 16 males, 2 attached to immature 

 females; collected by G. E. MacGinitie, from around the mouth and 

 anterior end of the giant ray Mohula lucasana Beebe and TeeVan; 

 off Santa Catalina Island, Calif.; October 3, 1946; occurring with 

 Pupulina Tninor. 



Types. — Holotype female, U.S.N.M. No. 85977; allotype male, 

 U.S.N.M. No. 85976. 



Diagnosis. — Posterior part of body in female longer than the an- 

 terior; a little shorter in the male. Both abdomen and processes of 

 the genital segment of female greatly elongated, the latter reaching 

 a little beyond distal end of caudal rami. Caudal rami of female 

 short and broad, only about one-fifth of the total length of the ab- 

 domen; linear in male, almost as long as abdomen. Basal portion 

 of outer piece of first maxilla not produced distally in female, hardly 

 so in male; inner piece of male with minute spine near distal outer 

 margin. Male maxilliped with large curved, clawlike process at its 

 base. Posterior ventral accessory processes large membranous lobes 

 in female, not so well developed in male. Leg 4 with inside spines 

 on segments 2-4. 



Description. — Female (pi. 14, fig. 1) : Measurements of holotype: 

 Total length about 14.8 mm.; length of cephalothorax, 6 mm.; pos- 

 terior part of body, 8.8 mm. ; length of carapace, 5.2 mm. ; width of 

 carapace, 6.0 mm. Total length of paratype, 14.5 mm.; width of 

 carapace, 6.0 mm. 



Carapace a little wider than long; anterior and posterior margins 

 only slightly curved, sides well rounded. Anterior sinus hardly dis- 

 tinguishable ; posterior sinuses deep. Dorsal pattern of carapace
