SOTEE : O'S NEW NON-MARINE SHELLS FROM NEW ZEALAND. 237 



the interstices with numerous microscopic incremental striae ; base 

 microscopically distantly spirally lirate. Colour fulvous, radially 

 ornamented with ziczac bunds of rufous at about the same distance 

 apart as the riblets. Epidermis tliin, not shining. Spire convexly 

 conoidal, with a blunt and rounded apex. Protoconch formed by 1^ 

 smooth flat whorls, which are microscopically finely spirally striate. 

 Whorls 4J, slowly and regularly increasing, flatly convex, the last 

 distinctly angled at the periphery, base rounded, umbilical region 

 slightly impressed. Suture not deep. Aperture somewhat oblique, 

 lunar; columella but little callous and extended over the umbilical 

 region. Peristome sharp, straight. Alt. 1'25, diam. 1-75 mm. 



Mab. — A few specimens were found by my son Alfred in a swampy 

 kahikatea bush near Wairangi, Waikato. 



The nearest allies to this species seem to be L. Francesci and 

 elaiodes, Webster, though decidedly very distinct from it. L. filicosta 

 is a lovely little shell and well characterized. Type in my collection. 



3. Flammulina (Phenacohelix) leptalea, n.sp. PI. XXII, Fig. 4. 



Shell small, subglobular, fragile, translucent, umbilicated, closely 

 costate. Sculpture formed by radial riblets, about 6 per millim. 

 straight above, slightly sinuate on the periphery and extending to 

 the umbilicus ; the costae are thread-like, sharp, the interstices with 

 numerous fine growth-lines which are decussated by equally fine and 

 close spiral lines. Colour light fulvous, with light ziczac markings of 

 brown. Epidermis very thin, not shining. Spire broadly conoidal, 

 with obtuse apex. Protoconch consisting of \\ smooth, convex whorls, 

 microscopically finely and densely spirally striate. Whorls 4 J, convex, 

 regularly increasing, the last indistinctly shouldered, and with the 

 periphery slightly flattened ; base rounded. Suture deeply impressed. 

 Aperture vertical, lunate ; peristome sharp and straight. Outer lip 

 convex, basal lip somewhat flattened ; columella subvertical, concave, 

 a little callous and partly spread out over the umbilicus, which is 

 moderate, deep, diameter -7 millim. Alt. 3'7 mm. ; diam. maj. 4-5, 

 min. 4 mm. 



Hah. — The type was collected by Mr. Strickland at Kaihu, 

 Hokianga. Waitakerei Range and Waiwera (H. S.). 



This species is closely related to F. Ponsonhiji, Suter, but is smaller, 

 much more globose and fragile, the colour-markings are generally of 

 a different pattern, the riblets more distant, and the umbilicus a little 

 narrower. Type in my collection. 



4. Flammulina (Allodiscus) Cooperi, n.sp. PI. XXII, Figs. 5-7. 



Shell small, orbicular, costate, imperforate, and with broad ziczac 

 streaks. Sculpture consists of close radial and sharp costse, very little 

 sinuous, 6 to 7 per millim., interstices with very fine incremental lines 

 which are crossed by indistinct fine microscopical spiral striae. Colour 

 fulvous with broad and distinct chestnut brown radiate streaks on the 

 upper part of the whorls, forming anastomosing ziczac lines on the 

 periphery and base. Epidermis thin, not shining. Spire low, broadly
