Messrs. Babor and Kostal describe and figure a new and interesting species of 

 Arion [vejdovskiji). The description is as follows : — "A. parvulum, in extensione 

 gracillimum, dorso rugis subtilibus densis ornato ; color dorsi flavo-rubellus, cupri 

 fere habitum imitans, laterum albidus capitis tentaculorumque ater ardesiacus, 

 summa doisiet clypei portione cinerea ; /on is lateralibusatris,tenuibusdistinctissimis, 

 figura lyriformi in clypeo simili ; pedis margine albo, haud tineolato : soleae parte 

 media pallida, lateralibus aurantiacis ; sudore luteo ; limacella nulla." 



I lab. : [arov prope Zavist' in Bohemia centrali. 



The authors have taken considerable pains in describing the anatomy. The 

 nervous system is typical of the genus. The pedal gland occupies two-thirds of 

 the length of the hod)-, and the caudal gland is considerably developed. The 

 generative system is described in detail. The hermaphrodite gland is large and 

 composed of two parts, each being formed by a number of large bluish-grey lobes; 

 the hermaphrodite duct is tolerably long and dilated towards its end, and in three 

 twisted segments, the last forming the seminal vesicle, not far from the albumen 

 gland. This gland is white and composed of little closely set tubes, slightly 

 pigmented at the entry of the hermaphrodite duct. The ovi-sperm duct (prostate 

 and oviduct) is folded upon itself, forming two and a half folds, it is white, with 

 purplish saculations. The sperm duct is rather short, with a cylindrical beginning 

 and ends in a considerable swelling, the retactor muscle attached to the swelling is 

 inserted in the posterior border of the pulmonary wall. In the swelling there 

 is a conical gland surrounded by a large fold in the form of a prepuce. The vas 

 deferens is small. There is a single vestibule from which the receptacular duct 

 opens as a broad pouch terminating in a small receptaculum seminus. 



A. vejdovskiji somewhat resembles A. intermedins, Norm., but, as the authors 

 point out, it differs slightly in colour and distinctly so in the generative system.

 Attention is drawn to the forgotten description by Swainson in a rare and early 

 volume of the Proc. Roy. Soc. of Van Diemen's Land of Astele snbearinaia, lately 

 renamed by Pilsbry Calliostoma adamsi ; the species is rehgured. Poirier is 

 quoted to show that Murex australis, Q. and G., is a prior title of the shell 

 better known as Murex paliniferus, Sby.
