Page 58. — In Mr. Cockerell's paper (P.Z.S., p. 221, 1891) he 

 mentions Aspidoporns, Fitz., as a " supposed genus, and founded 

 really on a species of Amalia" under the Arionince. I never 

 for a moment regarded either Tetraspis, Hagenm, or 

 Aspidoporns as belonging to the Arionidoz, but in reproducing 

 Mr. Cockerell's classification, I was obliged to include them. 

 No mention is made of the latter genus under Amalice (loc. cit. 

 p. 223). 



Respecting the genus Phenacarion, Ckll., I have not, as yet, 

 been able to satisfy myself that there are sufficient anatomical 

 differences to constitute generic distinction. 



Page 60. — Mr. Cockerell thinks the A. empiricorum v. ruber, Moq., 

 is distinct from the red variety which occurs in this country, 

 whereas I think the two may conveniently be referred to one 

 variety. 



Page 61. — Evidently the identification of v. hibernus and v. aterrima 

 is incorrect, but this is Mr. Cockerell's error and not mine. It 

 was copied direct from his MS., and unfortunately has escaped 

 my notice or I should have made some note or correction. 



Page 62. — I am wrong in speaking of Mr. Cockerell as the first to 

 separate A. subfuscus from other Arions. Dr. Heynemann's 

 record was unintentionally overlooked. 



Page 63. — The synonym A. hortensis, Jeff., is, I think, correct; 

 Jeffreys undoubtedly included A. intermedins, Normand, 

 amongst his light-coloured and young A. hortensis. 



Page 66. — Probably A. hortensis v. leucophiza is only a synonym of 

 A. fasciatus — and as such I use it — but it has been regarded by 

 many writers as a var. of A. hortensis, and in using the word 

 I wished to show that if a form of hortensis, it was only a minor 

 of v. fasciatus, Moq.

Fauna fossile terziaria di Markusevec in Croazia. Con un elenco 

 delle Dreissensidae della Dalmazia, Croazia e Slavonia. Descritta 

 du S. Brusina. (Reprinted from the Proc. of the Crontian Nat. Hist. Soc, 

 vol. vii, 1892, pp. 113-210.) 



This paper consists of four sections, viz. : Preface ; I. Mollusca of the Congeria 

 Beds ; II. Mollusca of the Sarmatian Beds ; III. Appendix : List of the 

 Dreissensuhc of Dalmatia. Croatia and Slavonia. To these are added a short 

 Postscript and an Index to the species in pts. i. and iii. 



Markusevec is situated about seven and a half kilometers N.N.W. of Agram, 

 and the Congerian and Sarmatian Beds are usually referred to the Pliocene and 

 Miocene respectively ; but in his postscript the author states that there is some 

 doubt as to the actual geological horizon of the beds here in question.
