Lucifer sp. ? 



Eniwetok Atoll : Southwest Passage, leeward side of reef two miles 

 south of Rigili Island; surface light at night; May 24, 1946; L. P. 

 Schultz; 1 male, 2 females. 



These specimens belong to Hansen's Group B (1919, p. 56), but 



Figure 3. — Thelyca of species of Sicyonella: a, S. maldivensis Borradaile with a carapace 

 length of 7.8 mm., X 13.6; b, S. inermis (Paulson) with a carapace length of 8.1 mm., X 13.6.

 group. As a matter of fact, the petasma most nearly resembles 

 that of Lucifer orientalis Hansen (1919, p. 55, pi. 4, fig. 7,a-g), which 

 belongs to Group A. It is possible, though unlikely, that the speci- 

 mens are immature; in any case, the material is not in sufficiently 

 good condition or abundant enough to provide a detailed description.
