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

 abiding places of luauy hydroids; and it is interesting to note that the 

 three genera, ^ertularia^ Sertularella, 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, /!?. oper- 

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

 three species, I shall uot attempt to make specific determinations. 



" The genus Sertularella is represented by a species resembling in mode 

 of growth the 8. tricuspidata of Alder. Hydrothecse alternate, stout, 

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

 johnstoni of Murray. (Dieffeubach's Kew Zealand, London, 1843.) 



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

 creeping form, and many of the hydrothecse have only their upper i)or- 

 tions free, the lower portious 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."

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

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

 of Otago, New Zealand. Mr. Eussell'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 Lams 

 dominicaniis $ , Daption capensis, Casarca variegata, Gm., Podiceps cris- 

 tatus {austr alls, Gould) S ,Forphyriops crassirostris, Graj, Greadion carun- 

 culatus, 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 collectiou. 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.

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.
