232 PROFESSOR CHARLES CHILTON ON THE 



Genus VIBILIA. 



Vibilia antarctica Stebbing. 



Vibilia antarctica Stebbing, 1888, pp. 1290, pi. cl. 

 propinqua Walker, 1907, p. 6. 



Station 422, lat. 68 32' S., long. 12 49' W. ; 8 ft. vertical net, surface to 800 

 fathoms. 23rd March 1904. Two specimens, 10 mm. long. 



These specimens appear to be the adults of this species, which was described from an 

 immature form by Mr STEBBING. Dr A. BEHNING, who has worked out the Vibilidse of 

 the German South Polar and other Expeditions, informs me that this species appears 

 to be the typical Antarctic species, though extending also some distance north, and that 

 it is very close to V. propinqua, but is distinguished by the long carpal process and 

 the poor development of the eyes. I presume this is the same species as that recorded 

 by WALKER under the name of V. propinqua from the Discovery Expedition. 



Genus EUTHEMISTO. 



Euthemisto thomsoni Stebbing. 



Themisto antarctica G. M. Thomson, 1879, p. 243, pi. x.n, figs. 2 and 3. 

 Euthemisto thomsoni Stebbing, 1888, p. 1414, pis. cxxiv. and cxxv. 

 1910B, p. 655. 



Station 468, lat. 39 48' S., long. 2 33' E. ; "trawl, 2645 fathoms." 29th April 

 1904. One specimen, doubtless obtained from the surface. 



This specimen agrees closely with the description given by STEBBING in the 

 Challenger Report, and I give it under the name that is used both there and in his 

 recent report on the collections of the Thetis from Australia, without entering into 

 discussion of the validity of the actual name. 



IV. TROPICAL AND NORTH ATLANTIC SPECIES.

Synopia scheeleana Bovallius. 



Synopia scheeleana Bovallius, 1886, N. Ada. Soc. Upsal., ser. 3, vol. xiii.,

 Stebbing, 1888, p. 799, pi. cii. 



1906, p. 272. 

 Chevreux, 1900, p. 64.
