Dagalet Island. 



Now known as Matsu-shima. A small and little-known island 

 in the Sea of Japan, east of Corea. See Travels, p. 174, Adams 

 visited the island, which is inhabited or at least used as a Haliotu- 

 fishing station by Coreans, on the 28th of June, 1859. It is 

 densely wooded, with a central peak 4,000 feet high. In the 

 Travels, p. 178, a slug " with the mantle covering the whole of its 

 back" (probably PAt7o?ni/cws) and a Zua (Cochlicopa) are men- 

 tioned. In the paper on Japanese Helicidoe only two species 

 are given : 



Helix ( Canuena) luchuana Sowb. [?] . 



Helix (Patula) elatior A. Ad. 



It is the only locality for the latter species. The identification of 

 H. luhuana is doubtful. 



TSU-SIMA. 



Tsushima, in the Corean Strait, is a locality prolific in land 

 snails. Adams reports the following : 



Helix (Acusta) sieboldiana Pfr. 



Helix ( Camcena') orientalis A. and E. [The specimens recorded 

 were probably E. luhuana tsushimana IVIlldff.]. 



Helix (Plectotrojns) ciliosa Pfr. [?]. 



Helix (Plectotropis) squarrosa Gld. [??]. 



Helix {Plectotrojns) troclmla A. Ad. 



Hyalina ? nitida Mill, [only record from Japan. Probably 

 wrong] . 



Hyalina (lEci'ocystis) rejecta Pfr. [only record from Japan. 

 Probably wrong]. 



Hyalina ( Conulus) stenogyra A. Ad. [Kaliella'] . 



Clausilia sieboldi Pfr. 



Clausilia stimpsoni A. Ad. 



Nangasaki (Nagasaki). 



In addition to the species given below, Adams states in his 

 Travels that he got Hadra peliomphala, Satstima japonica and 

 Acusta sieboldiana at Nagasaki (p. 268). The first two are im- 

 probable. 



Helix (Acusta) conispira Pfr.
