probably of Bala age, as T. antiquus, botb from a collection sent by 

 Mr. J. B. Morgan, of Welshpool, to Prof. Lapwortb for identi- 

 fication. A list of the species of Phyllopora, hitherto described from 

 Lower Silurian beds, and of both Upper and Lower Silurian forms 

 of Thamniseus, was added, and the relations of the various known 

 species to those described in the present paper were discussed at some 

 length.

" On some new or imperfectly known Madreporaria from the 

 Great Oolite of the Counties of Oxford, Gloucester, and Somerset.'' 

 By R. F. Tomes, Esq., F.G.S. 



The main object of the present paper, which is supplementary to 

 one already published in the Quarterly Journal (vol. xxxix. p. 168), 

 was to describe a section of the Great Oolite at Milton, in Oxfordshire, 

 another at the Lime-kiln quarry near Cirencester, and some out- 

 crops of the same beds in the neighbourhood of Bath, on Farley 

 Down, Combe Down, and Hampton Down, the localities from which 

 so many of the types of corals described by MM. Milne-Edwards 

 and Haime had been derived. Lists of the corals obtained from par- 

 ticular beds in each of the sections mentioned were given, and several 

 of these corals were described as new, remarks being appended as 

 to a few previously described forms. In conclusion, a brief descrip- 

 tion w T as added of the conditions under which the coralliferous de- 

 posits in the neighbourhood of Bath had been formed, and of their 

 probable correlation with the Great-Oolite strata of Oxfordshire.

On a new Genus of the Family Sarcopsyllidae. 

 By Wladimir Schimkewitsch. 



In the month of May 1884, N. A. Majew sent me from Turkestan 

 a considerable number of specimens of a still undescribed flea, 

 which attaches itself, after the fashion of a mite, to the bodies of 

 cattle, aud causes an exceedingly serious injury to the herds feeding 

 in the mountain-valleys of the Tjan-Schan. The statements pub- 

 lished in the Turkestan journals, and likewise communicated to me 

 by Majew, lun as follows: — The distribution of this parasite is con- 

 fined to the valleys of the Tjan-Schan and the Baissaur mountains 

 (the source of the river Tschilika). It also frequently occurs in 

 Taschkent and Tsischgent, upon cattle driven there for sale. The 

 parasite appears in the autumn, when snow is already lying upon
