ON THE ANATOMY AND SYSTEMATIC POSITION OF 



SOME RECENT ADDITIONS TO THE BRITISH 



MUSEUM COLLECTION OF SLUGS. 



By WALTER E. COLLINGE, F.Z.S., 



Mason University College, Birmingham. 

 (Plates iv — v.) 



The specimens enumerated in the following pages are some I have 

 recently received from Mr. Edgar A. Smith of the British Museum, 

 to whom my best thanks are due for his kindness in placing the same 

 in my hands, and also for the facilities he has given me for examining 

 the collections under his charge. I also wish to express my best 

 thanks to Dr. Ad. S. Jenson, the able Director of the Malacological 

 Section of the Zoological Museum of the University of Copenhagen, 

 for his kindness in permitting me to examine the type specimens and 

 dissections of TebemioxMorus australis, Bergh, and for the duplicate 

 specimens he has so generously sent me for purposes of dissection. 



ATOXON, Simr. 



Atoxon lineatum, Simr. 



^a?>.^Somaliland, East Africa. Two specimens collected by E. 

 Lort Phillips, Esq. 



These are both immature examples of this species. The repro- 

 ductive organs were not developed, but a comparison of the two 

 individuals with the description and figures given by Simroth (15) 

 leaves little doubt as to their identity. 



Length (m alcohol) 36.5 mm.
