702 MESSES. S. S. BUCKMAN AND E. WILSON [Nov. 1 896, 



Pleuroceras aff. nudum (Quenstedt). — The species is between 

 Pleuroceras vittatum, Phillips, ' Geol. Yorkshire,' pi. xiii. fig. 1, and 

 Pleur. nudum, Quenstedt. ' Der Jura/ pi. xxi. fig. 3. It is, however, 

 without the tubercules shown in the first species, particularly the 

 inner row, while it is much more distantly costate than the other, 

 and presumably a more robust shell than Quenstedt had to figure. 



Rhynchonella dundriensis, S. Buckman. — The type is in the 

 Bristol Museum, and no other specimen has been found at Dundry. 

 The appearance of the Dorset specimens suggested that the species 

 lived in the Humpliriesiani hemera, the given locality, Bradford 

 Abbas, being often applied somewhat indefinitely by the working 

 fossil-collectors. However, there are no strata of the LTumphriesiani 

 hemera at Dundry ; and so the date now assigned is more likely to 

 be correct, both for Dundry and Dorset. 



Terehratula aff. infra-ooliihica, E. Deslongchamps. — The speci- 

 mens mentioned by this name agree closely with examples of 

 T. infra-oolithica from Conde-sur-Sarthe, kindly given to me by 

 Prof. Bigot. They differ in the smaller size of beak and foramen, 

 and a slightly more pronounced carination of the perforate valve. 

 Both the Dundry and Prench forms differ appreciably from the 

 Dorset specimens which have hitherto been identified as T. infra- 

 oolitliica. 



Zeilleria anglica (Oppel). — In his 'Juraformation,' p. 425, §53, 

 No. 216, Oppel gave this name to a shell which he collected at 

 Burton Bradstock with Amm. opalinus, torulosus, and subinsignis. 

 He says the specimens agree remarkably (' stimmen auffallend ') with 

 the species figured by Davidson,Mon.Brach. (Pal. Soc.) vol. i. Append, 

 tab. A, figs. 10-13. from the Inferior Oolite of Dundry. There are, 

 however, certain differences to be noted in these shells. The Burton- 

 Bradstock specimens, which are from a lower horizon, are certainly 

 more lenticular, have more convex valves, a more prominent umbo, 

 and a more distinctly separated beak, with a larger foramen. This 

 Burton Bradstock shell agrees better with what Deslongchamps has 

 figured as Terehratula (Waldheimia) Lycetti, Pal. Eranc., Brachio- 

 podes, pi. xlvii. figs. 4-10 ; but this is not the Lycetti of Davidson, 

 which is a more elongate shell. As Oppel did not figure his shell, 

 but gave a reference to Davidson, and as Davidson's shell has been 

 figured by the name anglica, and known by that appellation so long, 

 it is desirable to leave it untouched ; but the Burton Bradstock 

 shell may be distinguished as Zeilleria Oppeli. 



Zeilleria Oppeli, S. Buckman. 



1856. Terehratula anglica, Oppel, pars, 'Juraformation,' p. 425. 

 1862. Terehratula {Waldheimia) Lycetti, Deslong. (non Dav.) ' Brachiopodes Terr. 

 Jurass.' pi. xlvii. figs. 7 & 9. 



Description. — A subpentagonal shell with somewhat gibbous 

 valves uniting in an almost sharp margin. Beak fairly incurved, 

 distinct, foramen rather large, beak-ridges and area fairly pro- 

 nounced.
