HYPERIIDAE , 73 



Remarks. In all these specimens the antennae are about as long as the head, some- 

 times a little less, sometimes a little more; except in one specimen of no. i where they 

 are considerably longer (head n mm., antennae 20 mm., total length 48 mm.); they 

 always arise close together, never more than 1-5 mm. apart in the largest specimens. 

 The number of ventral spines is constant (two pairs). 



No. 5 is noted as being "completely transparent". Woltereck(ioo3, p. 452) found rows 

 of regularly spaced chromatophores on the edges of the peraeopods and the dorsal keels. 



Nos. 3, 4, and especially 5 and 6, extend the known distribution far to the south. 



Distribution. North Atlantic, 5o°N; Indo-Pacific (Zanzibar and East Indies), 

 4 N-io° S. 900-2200 m.

Occurrence: 1. St. WS Hoetjes Bay, South Africa. 1 adult <$ 12 mm., 2 cJc? (penult, instar) 11 mm., 

 4 $$ 8-1 1 mm., from Medusae. 

 2. St. WS 95. Between Falklands and South America. 1 £ (penult, instar) 9 mm., 

 12 $$ 8-10 mm. (the larger ovig.). 



Remarks. In the Terra Nova Report I maintained that gaudichaudii was not separable 

 from galba, and further that spinigera and antarctica were also synonymous. Since, 

 however, I have seen the specimens in the present collection which are obviously re- 

 ferable to the form spinigera, I am of opinion that spinigera ought to be kept separate 

 from galba. 



Distribution. Mediterranean; North Atlantic, southwards to i7°N; South 

 Atlantic, northwards to 26^° S; Arctic and Antarctic Oceans; Indo-Pacific.
