forth, as in Cotylorhiza and Aurelia, as unpaired tongue- 
shaped lobules, but in pairs as in Discomedusa. The annular 
vessel is already completely closed, but the buccal arms, 
abundantly beset with tentacles, are still simple and undivided. 
Probably the preceding Ephyre, which have not yet been 
observed, agree with those of Cotylorhiza. 
XXIT1.— The Lepidoptera collected during the recent Expedi- 
tion of H.M.S. ‘ Challenger.—Part I]. By Artaur 
G. Butter, F.L.S., F.Z.8., Assistant Keeper, Zoological 
Department, British Museum (Natural History). 
THE first part of the Lepidoptera (which at the time I sup- 
posed to be the complete collection) obtained by the natura- 
lists of H.M.S ‘Challenger’ appeared in the ‘ Annals’ for 
June 1883, pp. 402-428 ; since the publication of that account, 
which embraced the species obtained in the Philippine, Aru, 
Admiralty, Fiji, and Friendly Islands, series have been re- 
ceived which were collected in the islands of St. Thomas, 
Bermuda, Rat Island, Ké Dulan, Ternate, and Amboina, 
amounting in all to one hundred and two species, which have 
yet to be recorded *, 
The collections from St. Thomas and Bermuda being from 
the New World, are here treated separately from those of the 
other islands. ‘They are as follows :—

Nymphalida.

1. Anosia leucogyne, sp. n. 
This is the West-Indian form of A. pleatippus of North 
America, from which it chiefly differs in the external black 
border of the secondaries of the male being either unspotted 
or very imperfectly spotted with white; the female also is 
usually (though not invariably) paler, and has the outer border 
* In an envelope were numerous specimens of Pyrameis carye, Hiibn., 
two damaged specimens of Leucania decolorata, Blanch., and two unrecog- 
_ nizable Micro-Lepidoptera from Juan Fernandez, taken on the 14th and 
15th November 1875; these I have not entered in this List.
