THE VOYAGE OF H.M.S. CHALLENGER. 
Part XXIX. — This Paper is the first part of a Report, by Professor William 
Turner, F.R.S., on the Bones of the Human Skeletons collected by the 
Expedition, and deals with the Crania. Professor Turner has not limited the 
Report to a description of the Crania actually collected by the Expedition, but 
has examined along with them numerous skulls from other collections, and 
has drawn certain general conclusions bearing on the Ethnology of the races. 
The Manuscript containing the descriptions of the Crania was received in 
July 1883, whilst the last two chapters referring to the general conclusions 
were received in July 1884. 
Part XXX. — Shortly after the return of the Expedition to England, 
George Busk, Esq., F.R.S., consented to prepare a Report on the collection of 
Polyzoa. 
The present Memoir is the first instalment of the Report, and treats of the 
Cheilostomata. The Manuscript was received in batches between the 7th 
February 1883 and the 16th July 1884. Mr. Busk promises the second and 
concluding part of his Report in the course of a few months.
