Description of a new Species of Slug of the Genus Janella. By W A L T E R E. COLLINGE, Demonstrator of Zoology and Comparative Anatomy, Mason College, Birmingham1. [Received May 8, 1894.] I have recently received from Mr. H. Suter, of Christchurch, New Zealand, a series of Slugs belonging to the genus Athoraco-phorus, Gould, better known to European malacologists under the generic name of Janella. Although this latter name is preoccupied by a synonym, I am decidedly in favour of its retention, for reasons set forth by Professor Cockerell2. Of the above specimens, six are J. bitentaculata, Q. & G., four J. papillata, Hutton, and two I am here describing as belonging to a new species, which I shall term J. maculata. To what extent J. bitentaculata varies I am not aware; certainly no two of the above six specimens are alike. The two examples which I am naming J. maculata Mr. Suter included with J. bitentaculata ; but he has evidently not examined the series, or I feel sure he would have noticed the very distinct form and colour of these particular two. 1 Communicated by E.
