SPECIES PRESENT IN THE SAMPLES 269 



Conchoecia lophura Miiller. 



For synonymy and description see Skogsberg, 1920, p. 689, fig. cxxxi. 



Single adults of this species were present in samples from Stations WS 976, 986 and 997. There 

 were two juveniles in samples from WS 986 and one from Station WS 996. 



Conchoecia loricata (Claus). 



Conchoecissa loricata Claus, 1894, p. 4; pi. 3, fig. 24-30. 

 Cotichoecia loricata Miiller, 1906, p. 95; pi. 22, figs. 1-9. 

 C. loricata loricata Miiller, 1912, p. 80. 



A few specimens of adults and juveniles of this species occurred in samples taken below 250 m. at 

 Stations WS 976-8, 986, 996 and 997. 



Miiller (1906) distinguished two varieties of the species, which he called var. typica and var. minor. 

 The latter differed from the former in being smaller, having only twelve pairs of spines on the proximal 

 seta of the antennule instead of about twenty-two, and having less marked striae on the shell. In a 

 later publication (19 12) he refers to the former as C. loricata loricata. The present material would 

 appear to fall within the scope of C. loricata loricata though it has fewer spines on the proximal seta. 

 The range of variation and status of the ' varieties ' cannot be determined before a considerably greater 

 bulk of material has been examined. 



Conchoecia macromma Miiller. 



Conchoecia macromma Miiller, 1906, p. 79; pi. 17, figs. 11-22. 

 C. macromma Miiller, 1912, p. 75. 



A single adult female of this species was present in the 1000-750 m. sample from Station WS 986. 



Conchoecia mamillata Miiller. 



Conchoecia mamillata Miiller, 1906, p. 60; pi. 16, figs. 1-9; pi. 35, fig. 8. 

 C. mamillata Miiller, 191 2, p. 70. 



A single adult female was found in the 1000-750 m. sample from station WS 976. 



(?) Conchoecia mollis Miiller. 



Conchoecia mollis Miiller, 1906, p. 106; pi. 24, figs. 1-10 and 13. 

 C. mollis Miiller, 1912, p. 85. 



A single adult female was found in the sample collected between 1000 and 750 m. at Station WS 996, 

 which if not C. mollis itself is closely related to it. Existing descriptions only make it possible to 

 distinguish the males of the group of species allied to C. mollis, and until more detailed descriptions of 

 the females are available, doubt must remain regarding the identity of this particular specimen. 



Conchoecia nasotuberculata Miiller. 



Conchoecia nasotuberculata Miiller, 1906, p. 83; pi. 18, figs. 25-30. 

 C. nasotuberculata Miiller, 1912, p. 76. 

 This species occurred in large numbers at Stations WS 976-8, 986, 996 and 997. Distributional 

 data of this species will be discussed later in the report.
