MARINE AAIPHIPODA IN MICRONESIA — BARNARD 529 



Type locality: Reisli station E-40, Eniwetok Atoll, Aug. 27, 1956. 



Relationship: The only other species of Lemhos bearing an inflated 

 second article on gnathopod 2 is L. kergueleni (Stebbing 1888, pi. Ill), 

 but the new species differs from it markedly in the first gnathopod and 

 the rounded first coxa. 



No other known species of the genus has a first gnathopod similar to 

 L. bryopsis. 



A single female was associated with this male animal in Station 

 E-40 but the writer considers that it belongs temporarily with L. 

 aequimanus. 



Distribution : Eniwetok Atoll, Marshall Islands. 



Lemhos processifer (Pirlot) 



Figures 28 g-m 

 Bemlos processifer Pirlot, 1938, pp. 330-334, figs. 147-149. 



Material: Abbott stations 31-D-2 (2), 76-H-3 (3), 124-D-3 (2), 

 128-C-5 (1), 160-165-J-5 (1), 176-G-4 (3), 177-G-5 (2), 179-184- 

 M-1 (3); ? Reish station E-163 (1 female). 



Remarks: Females and juveniles of this species have the enlarged 

 sixth article of gnathopod 1 similar to the male, and article 5 is short- 

 ened, so that these animals are relatively easy to separate from females 

 of Microdeutopus tridens (figure 27/) . 



Pirlot's (1938) figure 149 of the female second gnathopod is really 

 the first gnathopod of a small female. In the present materials gnath- 

 opod 2 of the female is similar to that of the male gnathopod 2. 



Lemhos processifer and L. intermedins Schellenberg (1938a) appear 

 identical except for the pointed first male coxa of L. intermedins. 

 None of the specimens at hand shows any tendency to a pointed first 

 coxa; because this feature is presently a necessary part of any key to 

 Lemhos, L. intermedins from the Hawaiian Islands and L. processifer 

 from Micronesia and the Celebes are conserved; nevertheless, their 

 life histories should be fully studied for evidence of mtergradation and 

 subspeciation. 



For future reference it may be noted that L. intermedins was 

 described in June of 1938 and L. processijer in October of 1938. The 

 date of pubUcation apparently is missing on Pirlot's paper, at least on 

 the several copies from U.S. libraries available to the writer. The 

 publisher, E. J. Brill, Ltd., Leiden, has kindly informed me that their 

 records show October 1938 as the publication date of Pirlot's paper. 



Distribution: Celebes; Ifaluk Atoll, Caroline Islands.
