THE FOSSIL ANOMODONTIA OF SOUTH AFRICA. 

 Sir, — In the Geological Magazine, p. 369, is a notice of a paper 

 by Prof. Seeley on Procolophon, in which he remarked on the 

 presence of tioo distinct nares in this fossil. At the time the fossils 

 "were sent to Professor Owen from this museum, we had not received 

 any but specimens more or less defective, especially at the apex, 

 but I had already requested Mr. Donald White, on whose farm at 

 Donnybrook they have as yet only been found, to try to get some 

 examples which would show the nostrils. This he has done ; and 

 I have now before me a specimen in which the two distinct nares 

 are excellently shown. With regard to Professor Seeley's idea that 

 the Procolophon is a parent type from which the dental modifica- 

 tions of Anomodontia have been derived, I would point out that 

 Tafelberg, on which the farm Donnybrook is situated, occupies a 

 geological position much higher than that of the Karoo-beds in 

 which Dicynodon is found. Hitherto this Tafelberg, formed of 

 horizontal beds, is the only place where ProcolopJwn has been found, 

 so that it is improbable that it can have been the parent tj^pe of the 

 Anomodontia, without we make the assumption that it appeared at a 

 much earlier time than that for which we have any evidence. Above 

 the beds of the Tafelberg rise the equally horizontal and conformable 

 beds of the Stormberg, and in neither of these, so far as I know, 

 have any Dinosaurs or Anomodontia been found.

PALEOZOIC CEPHALOPODA. 



Sir, — Will you allow me to ask my brother-geologists, through 

 the pages of your Magazine, for the loan of any examples of British 

 Palfeozoic Cephalopods which they may think of sufficient interest 

 to be noticed in a general work on that group, or likely in any way to 

 throw light upon the subject. Having been favoured with a Govern- 

 ment grant in aid of the publication of a "Synopsis of British Fossil 

 Cephalopoda," 1 hope very shortly to offer the first part for subscrip- 

 tion, which will include the Palaeozoic portion and be amply illustrated, 

 I am desirous of making it as complete an account of our British 

 fauna as possible, and this can only be done by the kind co-operation 

 of those who have valuable specimens in their collections, which, if en- 

 trusted to me, I need hardly say, will be returned in good condition.

THE BOULDER CLAY OF YORKSHIRE. 



Sir, — Until recently, I was not aware that the existence of shells 

 in the " Purple " Boulder-clay north of Flambro (the " Purple clay 

 without chalk" of Mr. S. V. Wood), had already been pointed out 

 in a paper by Mr. Leckenby " On the Boulder-Clay of East York- 

 shire," Brit. Assoc. 1864, and more recently by Dr. J. Gwyn 

 Jeffreys in a " Note on the so-called Crag of Bridlington " (Rep. 

 Brit. Assoc. 1874). By a clerical error, the wrong initials have been 

 affixed to my name in the paper published in your last Number, p. 509.
