5. Description of a new Species of Slug of the Genus 

 Janella. By Walter E. Collinge, Demonstrator of 

 Zoology and Comparative Anatomy, Mason College, 



Birmingham 



[Received May 8, 1894.] 



I have recently received from Mr. H. Suter, of Christchurch, 

 Xew Zealand, a series of Slugs belonging to the genus Athoraco- 

 phorm, 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 Cockerell 2 . 



Of the above specimens, six are J. bitentaculata, Q. & G., four 

 J. papiUata, 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 -/. 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.
