Vessel : Station Occurrence 



Hugh M. Smith __ 178 1 male, 1.90 mm. 



Do 144 1 male, 2.28 mm. 



Remarks: Only two males of this species 

 were found. The right posterior lateral pro- 

 trusion of the thorax is characteristic. This 

 protrusion exceeds the end of the genital seg- 

 ment and its tip, as seen in dorsal view, is 

 irregular (fig. 4). In lateral view the distal 

 end appears to be somewhat truncate (fig. 5). 

 A small, posteriorly directed hook arises from 

 the right side of the genital segment (fig. 4). 

 The basal tooth of the gnathal lobe of the man- 

 dible is tricuspate (fig. 6). The thumb of the 

 chela of the right fifth foot has a stout spine 

 at its tip. 



In regard to the above indicated synonymy, 

 Sars (1903) redescribed C. armata (Boeck, 

 1873) and pointed out that C. pectlnafa 

 (Brady, 1878) is a synonym of the former spe- 

 cies. C. armata is a north Atlantic species 

 which occurs along the east coast of the United 

 States as far south as off Beaufort, North Caro- 

 lina (Fleminger and Bowman, 1956), and along 

 the coast of Europe probably as far south as 

 off Spain. It has also been reported from the 

 Mediterranean Sea (Rose, 1934) and from the 

 Adriatic Sea (Hure, 195.5). 



I have examined specimens identified by Es- 

 terly (1905) and labeled C. biplnnata 9, C. pec- 

 tinata S , which were loaned to me by Dr. Abra- 

 ham Fleminger of the Scripps Institution of 

 Oceanography. Included in the vial were two 

 females, C. bipinnata. Esterly's figure of the 

 fifth foot of his female C. pectinata is prob- 

 ably that of a stage V female C. bipinnata, a 

 species which also occurred in his collections. 

 The figure of the genital segment of his male 

 C. pectinata is clearly referable to C. bipinnata. 

 Esterly stated in regard to C. bipinnata that he 

 did not find the male of this species. 



Mori (1937) reported only the male of C. 

 pectinata from Japanese waters. His figures 

 and description of this species indicate that it 

 is actually C. bipinnata. The protrusion of the 

 right posterior lateral margin of the thorax, 

 the form of the hook on the right side of the 

 genital segment, and the structure of the fifth 



pair of feet all agree with those of C. bipinnata. 

 Mori also presented figures of male C. bipinnata 

 which are not unlike those of his C. pectinata. 



Dakin and Colefax's (1940) C. pectinata 

 (both sexes) which were questionably referred 

 to this species are also C. bipinnata. I have 

 examined specimens which were obtained from 

 the east coast of Australia and which are simi- 

 lar to the figures presented by these authors 

 for C. pectinata. These copepods are stage V 

 female and adult male C. bipinnata. 



As to other reports of C. pectinata from the 

 Pacific Ocean, Scott (1909) has previously 

 stated that Brady's (1883) figures of this spe- 

 cies "represents at least four distinct species, 

 none of which are identical with it" (C. pecti- 

 nata = C. armata). C. pectinata has also been 

 reported by Honjo (1952) and Hon jo et al. 

 (1957). As the species is included in lists, 

 without descriptions or figures, these records 

 too are questionable and in need of confirma- 

 tion.

Vessel : Station Occurrence 



Hugh M. Smith __ 31 2 males, 2.14, 2.18 



mm. 



Do 63 1 female, 2.55 mm.; 



2 males, 2.26, 

 2.28 mm. 



Remarks: The female has a long and sym- 

 metrical genital segment (fig. 8) which is pro- 

 duced on the ventral side (fig. 9). The fifth 

 feet are slightly asymmetrical and terminate 

 in two rather long, but unequal, points (fig. 

 10). The thorax and genital segment of the 

 male are symmetrical (figs. 11, 12). The basal 

 tooth of the mandible ends in three approxi- 

 mately equal cusps. The right fifth foot is 

 chelate (fig. 16).
