land coast by the species Boltcni, the stems of which are the favorite 

 abidiug places of mauy hydroids; and it is iuterestiiig to uote that the 

 three genera, Sertularia, SertulareUa, and Lafoea., which are almost in- 

 variably represented on our New England species, are also represented 

 on the stem of this southern specimen. 



'' The species of Sertularia is very close to, if not identical with, IS. oper- 

 culata of Linnaeus ; but there being no gonothecse present on either of the 

 three species, I shall not attempt to make specific determinations. 



" The genus SertulareUa is represented by a vspecies resembling in mode 

 of growth the S. tricuspidata of Alder. Hydrothecse alternate, stout, 

 and with a tricuspid rim. Possibly this is identical with the Sertularia 

 johmioni of Murray. (Dieffenbach's New Zealand, London, 1843.) 



" The third species is probably a member of the genus Lnfoi'a; it is a 

 creeping form, and many of the hydrothecse have only their upper por 

 tions free, the lower portions reclining upon the stolon. The ascidian 

 bearing these hydroids was collected at Port Chalmers, New Zealand, 

 in January, 1875, by Dr. E. Kershner, U. S. N." 



II. 



A considerable collection was also made by Mr. Israel Eussell, one of 

 the photographers to the New Zealand party, mostly from the province 

 of Otago, New Zealand. Mr. Kussell's collection includes a number of 

 Maori implements, with some supposed to belong to a still older race 

 (perhaps the Maori-ori). His bird-skins represent specimens of i«r?/s 

 dominicanus 9 , Daption capensis, Casarca variegata, Gm., Podiceps cris- 

 tatus {g.ustralis, Gould) $ , Porpliyriops crassirostris , Gray, Creadion carun- 

 culatits, and two pigeons and a parrot, as yet undetermined. Besides 

 these, there are a number of New Zealand birds preserved in alcohol, and 

 a large collection of the bones of the moa. 



Other departments of natural history are well represented in Mr. 

 Russell's collection. There are a large number of fossil shells from Lake 

 Wakatipu, New Zealand, and of recent forms from the same pit in 

 which the Maori implements were found. Also, a considerable collec- 

 tion of plants, and of insects, Crustacea, and small vertebrates which 



have not yet been studied. 



IIL 



Mr. Edwin Smith, United States Coast Survey, chief of the Chatham 

 Island party, sends three skulls, two of Maoris and one of a Maori-ori, 

 for the authenticity of which he vouches.
