COLLINGE : NEW HAWAIIAN SLUGS. 295 



and tlie head expanded. The oviduct is short and hent upon itself, 

 thus CO (Fig. 4, ov.). The albumen gland is very large. The herm- 

 ajihrodite duct and gland are both small. 



Externally the species is not unlike a small example of A. ater, 

 Cllge., and differs only from dark forms of A. g agates, Drap., in its 

 j)rominent keel. 



I have much pleasure in associating with this species the name of 

 Mr. J. P. Babor, of the Institute of Comparative Embryology, in the 

 University of Prague. 



2. AgKIOLIMAX L.T3VIS, Mlill. 



Small collection from Lihue, Kauai (2,000 feet), and from Haleakala 

 (5,000 feet). 



3. Ageiolimax Bevenoti, n.sp. 



In a collection of specimens from Kauai (4,000 feet), Honolulu 

 (2,000 feet), and another from Haleakala (5,000 feet), Mr. Perkins 

 sends a large number of small specimens of Agriolimax. I have 

 dissected a number of these, and for some time was veiy doubtful 

 whether or not to remove any of them from A. Icevis. Dr. Simroth 

 has very kindly examined some of these and given me his opinion 

 upon them : he thinks the species is scarcely distinguishable, and that 

 these specimens are nearly related to A. Icevis, Miill., and^. campcstris, 

 Binney, from North America, A. hjperboreus, Wstr., from Behring 

 Strait, and A. agrestis, L., from Northern Siberia. 



I have made a careful examination of this material, and, as 

 previously stated, I think there are sufficient reasons for separating 

 some of these specimens from any of the above-mentioned forms. 

 I have, therefore, named those from Kauai (4,000 feet) A. Bevenoti, 

 after my colleague Professor Clovis Bevenot, to whom I am much 

 indebted for the assistance he has so often given me with regard to 

 Italian malacological literature. 



Animal not unlike A. Icevis, Miill., but slightly darker in colour. 

 Length (in alcohol) 16 mm. 



Anatomy. — The only parts of the reproductive organs which I have 

 been able to clearly make out are the form of the free-oviduct and 

 receptaculum seminis. In the three specimens dissected this latter 

 organ was always folded, as shown in Pig. 9, r.s., and the free- 

 oviduct showed two small pouch-like diverticula. The reproductive 

 organs were, unfortunately, not in a very mature condition. 



4. Tebennophorus striatus, Hasselt. 



There are numerous examples of this species collected at Honolulu 

 (2,000 feet), and Lihue, Kauai (2,000 feet).
