PHRONIMIDAE 285 



Phronima atlantica, Guer. 



Vosseler, 1901, p. 21, pi. ii, figs. 1-10. 

 Stephensen, 1924, p. 121, chart 16. 

 Mogk, 1927, p. 131, chart 2. 

 Barnard, 1930, p. 422. 



Occurrence: 1. St. 39 05' N, 13 04' W. 1 3 8 mm., 1 $ 10 mm. 



2. St. 2 20' S, 12 45' W. 1 3 7 mm., 1 ? 8 mm. 



3. St. 87. South-east Atlantic. 5 33 5-10 mm., 8 ?$ and juv. 4-10 mm. 



4. St. 89. South-east Atlantic. 9 33 6-10 mm., 9 $$ and juv. 4-14 mm. 



Remarks. Propagation appears to take place during both summer and winter, but 

 chiefly in summer (Vosseler, p. 26; Stephensen, p. 124). Mogk (p. 131) records 33 in 

 the penultimate stage in August to October. Vosseler (p. 26) refers to the possibility 

 of there being two broods a year, which is interesting in comparison with the remarks 

 made under sedentaria. 



None of the present 33 are fully adult, even the largest from St. 87 and 89, which 

 are even larger than the normal size recorded, although only in the penultimate stage. 



Distribution. Mediterranean; North and South Atlantic, 4i°N-40°S; Indian 

 Ocean, 28°-39° S; Pacific Ocean, 37 N-30 S and Chilean coast; Antarctic, 65 S, 

 88° E. 



Phronima curvipes, Voss. 



Vosseler, 1901, p. 27, pi. iii, figs. 1-3. 

 Stephensen, 1924, p. 126, fig. 52, chart 17. 

 Mogk, 1927, p. 137, chart 6. 



Occurrence: 1. St. 3 50' S, 12 54' W. 1 ovig. ? 13 mm. 



2. St. 81. South Atlantic. 1 ? 13 mm. 



3. St. 285. East mid- Atlantic. 1 914 mm. 



4. St. 288. East mid-Atlantic. 1 ovig. <j> 12 mm. 



5. St. 296. East mid-Atlantic. 1 $ 1 1 mm. 



Remarks. The 3 of this species is known only from the Gauss expedition, and Mogk 

 expresses a certain hesitation in the identification. Ovigerous $? are known varying from 

 ii mm. (Stephensen), 14-16 mm. (Mogk), to 17 mm. (Vosseler); they have been found 

 in June to September (Stephensen) and September (Mogk). 



Distribution. Mediterranean; North and South Atlantic, 35^-34° S; Indian 

 Ocean (one record only from 5 S).
