IMagellan." In tho figure tbo last segment of the person, the first two and the fourth of the 

 pleon, are produced into dentiform processes. It is likely enough that it is identical ■with, 

 or at most a variety of the species next mentioned. " 64. Afi/7vs Huxleyamis, Bate. 

 Taken in tho Strait of Magellan." " 65. Tliemisto antarctica, Dana. Taken in numhers 

 in the towing-net between the river Plate and the Strait of Magellan, during a calm which 

 succeeded a violent gale, in November 1867." " 66. Jpliimedia Normani, n. sp. (PI. LIX. 

 fig. 7). Cophalou produced into a sharp-pointed rostrum. First three segments of pleon 

 having a sharp-pointed tooth on each lateral margin. Eyes subreniform. Superior and 

 inferior antennse of nearly equal length. Colour purplish. Length 4 lines. One specimen 

 of this species, named in honour of the Eev. A. IM. Norman, was dredged ofi' Elizabeth 

 Island in February 1867." The figure shows a perseon of six segments with only five side- 

 plates ! Neither figure nor description is adequate for the determination of a species. 

 "67. Caprella dilafafa, Dana. Taken in numbers on the screw of H.M.S. 'Nassau' in 

 August 1867," Dana's species is considered by Mayer to be the same as Caprella acutifrons, 

 Latreille.

Dr. Brandt supposes a piece of whale-skin beset with Cyami which he found in the St. Peters- 

 burg Museum to be the skin of the extinct Rhytiiia horealis bearing the parasite for which 

 J. F. Brandt proposed the genus Sirenocyamus. He notices the great similarity between 

 the specimens thus found and Cyamus ovalis, Koussel de Vauzeme, and Liitken subse- 

 quently came to the conclusion that the supposed " Cyamus Rhytinx " was actually Cyamus 

 ovalis, attached to the skin, not of Rhytina horealis, but of Balxna japonica.
