was removed from its enveloping integument. There were not 

 enough specimens to determine the coils of the intestine, but the 

 rectum was well seen. The retractor muscles of the eye-tentacles 

 are situated on the posterior end of the mantle, and the branchial 

 cavity, the heart lying on the anterior side. 



The generative organs were well seen and mounted. 



The penis is a simple, short, thick tube with a globose head 

 giving off a small, tightly-coiled, what may be termed flagellum, or 

 rather its homologue ; the vas deferens joins it on one side and 

 the retractor muscle on the other. The spermatheca is short, club- 

 shaped, and lies close against the free oviduct. The vas deferens is 

 very short. I could not find any excitatory organ, which Semper 

 shows exists in Agriolimax Icevis {vide p. 122, Moll. British Isles). 

 The generative organs are of the same type, only differing in minor 

 details. 



The peculiar character of this species is the strong lateral 

 grooves on the side of the foot^ running from the peripodial groove 

 upwards. Taylor's description of Agriolimax agrestis does not 

 apply to this species. The teeth of the radula are similar in form 

 to those of Agriolimax hyperhorea (Westerland) ; the laterals 

 being curved and aculeate, but there are far fewer of them. I 

 got the radula out in a very perfect state, and the formula is 

 17. 2. 12. 1. 12.2. 17, or 31-T.-31 ; in hyperhorea it is 42-1-42 , laterals 12 

 in number, marginals about 30; it shows the two species are very 

 close to one another. 



Jaw moderately arched with a small central projection. 



Shell thin, glassy, transparent, milky white, flat, elongately 

 ovate, widening in breadth gradually to the anterior edge, with 

 a rounded apex. 



[Note. — The specimens described above by Colonel Godwin- 

 Austen were found under stones in a small mountain stream at 

 High Hill Gompa. The smaller specimens (from tube No. 58) were 

 taken on the i6th July, the larger (tube SS) on the iTth September. 

 On the 29th March I had found under stones in the same loca- 

 lity two eggs which presumably belong to this species. They 

 were spherical, 2 mm. in diameter, and had very thick, tough, 

 laminated, membranous shells. Floating loose in the cavity of 

 the shell was an embryo in an early stage of development, roughly 

 spherical and showing a differentiation into a thin outer layer and 

 an inner cellular mass. These two eggs were placed in water in a 

 tube and kept in a room of the Trade Agency at Chang-lo. On 

 the loth April the embryos had begun to assume a slug-like form, 

 but they showed no haste to break through their shells, and it was 

 not until the middle of May that they introduced themselves to 

 the outer world. Although this collecting-ground was regularly 

 visited, no adult slugs were found until July.— F. H. Stewart.]
