6. St. 88. South-east Atlantic. 4 $$ 6-7 mm., 1 $ 7 mm., 5 juv. 5-6 mm. 



7. St. 89. South-east Atlantic. 13 $<$, 16 ?? 6-7 mm. 



8. St. 268. East mid-Atlantic. 2 S<S 7~7'S mm., 1 $ 6 mm. 



Remarks. Stephensen records breeding ?? in January, February, and June to 

 September; and young at all seasons. 



Distribution. Mediterranean; Atlantic, 53°N-43°S; Indian Ocean; Eastern 

 Pacific. 



Vibilia pyripes, Bov. 



Behning, 1913, p. 221 ; 1925, p. 494, fig. 62. 

 Stephensen, 1918, p. 52, fig. 17, chart 5, and p. 53 (grandicomis). 

 Barnard, 1930, p. 405. 

 Occurrence: St. 71. South-west Atlantic. 5 cTc? 7-8 mm. 



Remarks. The maintenance of grandicomis (Chevreux, 1900, p. 131, pi. xvi, fig. 2) 

 as a separate species seems very doubtful. 



Distribution. Tropical and sub-tropical Atlantic; Indian Ocean; Pacific. 



Vibilia cultripes, Voss. 



Vosseler, 1901, p. 121, pi. xi, figs. 6-18. 



Behning, 1913, p. 222; 1925, p. 495, figs. 63-67; 1927, p. 119. 



Stephensen, 1918, p. 53, fig. 18, chart 7. 



Occurrence: 1. St. 6° 55' N, 15 54' W. 1 <J 14 mm. 



2. St. 81. South Atlantic. 1 $ 16 mm. 



3. St. 256. South-east Atlantic. 2 SS 15 and 16 mm. 



4. St. 268. East mid-Atlantic. 2 ovig. ?$ 11-12 mm. 



5. St. 281. East mid-Atlantic. 1 c? 13 mm. 



6. St. 285. East mid-Atlantic. 1 <$ 14 mm. 



7. St. 298. East mid-Atlantic. 1 $ 1 1 mm. 



Remarks. The eyes in the c?c? are unusually well developed, being almost contiguous 

 on the top of the head. This development is even greater than in macropis and diminishes 

 still further the value of one of the characters which is quoted as distinguishing the 

 " Cyllopodidae " from the Vibiliidae. 



Distribution. Mediterranean; Atlantic, 49 N-6° S; Indian Ocean; Pacific. 



Vibilia sp. 



Occurrence: St. 268. East mid- Atlantic. 1 ? 10 mm. (damaged). 



Remarks. The identification of this damaged specimen is not at all certain. It is 

 clearly distinct from the specimen of viatrix, with which it was caught, in the sub- 

 rounded telson, the uropods, the somewhat gibbous forehead and the dactyls of peraeo- 

 pods 1-4. It is larger than previous records of gibbosa, but may possibly be this species, 

 which is known from the Atlantic between 30 N and 20 S (cf. Behning, 1927, 



P- ii5)-
