Dunwich. They were, of course, dead, but were still in their crypts. 

 Almost at the same time I received a letter from Mr. A. Mayfield, of 

 Mendlesham, stating that he had found odd valves of this species at 

 Lowestoft and Felixstowe. Thinking that perhaps it might occur on the 

 Lincolnshire coast, where the conditions are suitable, I wrote to Mr. C. S. 

 Carter, of Louth, who most kindly sent me examples of the shell collected 

 at Mablethorpe in 1900, and a specimen found in August, 1896, between 

 Minster and Warden Point, Sheppey. He stated that the shell had been 

 known on the Lincolnshire coast for twenty years, but that it had become 

 more abundant during the last few years. In the Journ. Roy. Micro. 

 Soc, 1907, part 4, p. 416, quoting from Zool. Anz., vol. xxxi. No. 7, 

 pp. 268-70, it is stated that C. Boettger had found this species near Sylt 

 and between the North Frisian Islands and the mainland, and that 

 E, Wolf had also found it near the East Frisian Islands. It has also been 

 recorded by MM. Dupuis & Putzeys from the coast of Belgium. It will 

 thus be seen that this species has a far wider distribution than was 

 formerly supposed, and that it must have been a member of our fauna for 

 some little time. A. S. Kennard. 



On the Original Drawings for the Illustrations in the 

 "HiSTORiA Naturalis Testaceorum Britannia" of E. M. Da Costa, 

 1778. {Read 8tk November, 1907.) — These were drawn and painted on 

 seventeen sheets of vellum. Moses Harris was responsible for the 

 sheet for pi. iii, which has his signature and the date November 24th, 

 1776, at the bottom left-hand corner. The sheets for the other sixteen 

 plates bear the signature of Peter Brown, but no date. The former was 

 and is fairly well known as an entomologist, and his " Aurelian or Natural 

 History of English Insects" is still referred to. He was also the author 

 of other works. The latter, as far as I know, was only responsible for one 

 work, the " New Illustrations of Zoology," and this is not often seen. 

 I do not think the engraver of these plates has been identified, and 

 probably more engravers than one were employed, as plates viii, ix, x, xi, xv, 

 and xvii were not reversed, as they should have been, and consequently the 

 figures have come out sinistral. These plates with additions and deletions 

 were afterwards re-engraved and used to illustrate Pulteuey's "Dorsetshire 

 Shells" in Hutchin's " History of Dorset," 1799. One figure appears on 

 Da Costa's plates which was not on the originals, viz. fig. 7 of pi. vi, 

 Monodonta crassa (Montfort) {T. lineatus, Da Costa), its place being taken 

 by a figure of Limncea, which appears on pi. v as fig. 17, the reversed view 

 of this species originally drawn being deleted. A. Reynell. 



MiTRA REGUEVIR0STRI8 ; NAME SUBSTITUTED FOR M. RECURVA, 



SowERBY. {Read \Oth January, 1908.) — By a curious oversight in the 

 Journal of the Linnean Society, 1889 (vol. xx, p. 396, pi. xxv, fig. 7), 

 I gave the name ' recurva ' to a striking form of Mitra received from the 

 late V. de Robillard, of Mauritius, although the name had been used by 

 Reeve for a very different species (Proc. Zool. Soc, 1845, p. 56) described 

 and figured in the Conchologia Iconica, vol. ii, pi. xxxvi, fig. 297. 

 I now propose to alter the name of the species to M. recurvirostris.

On Astarte mutabilis, with reversed hinge-dentition. {Read 

 10th January, 1908.) — The left valve of Astarte mutabilis, Searles Wood, 

 from the Pliocene (Coralline Crag) of Suffolk, exhibited by me on 

 January 10th, is very remarkable on account of having the hinge-dentition 

 of the right valve. In other respects it is quite normal. As instances of
