160 ANOGLYPTA. 



izontal ; outer lip thin, not expanded, having a projecting angle just 

 above the periphery ; columellar lip slightly thickened and expanded 

 toward the insertion. Type A. launcestonensis, pi. 29, fig. 16. 



Animal having the sole undivided ; upper surface granulated, the 

 granules arranged in indistinct rows on the back ; facial or lateral 

 grooves distinct ; tail pointed and flattened. Mantel edge thick, 

 developing a large left body-lobe in front of the respiratory pore, 

 and a triangular right one below and behind it. Genital foramen 

 upon the right lateral groove, below and behind the eye stalk. 



Jaw arcuate, with a slight median projection ; very finely, irregu- 

 larly striated vertically (pi. 47, fig. 6). 



Radula having all of the teeth unicuspid. Central and lateral 

 teeth (pi. 48, fig. 10) having the basal-plates contracted on the outer 

 margin, forming a sort of socket for a projection on the inner mar- 

 gin of each succeeding plate. Marginals with long, broad, oblique 

 cusps, becoming shorter on the outer ones (pi. 48, fig. 11, three 

 groups of marginal teeth, the right hand group from the outer edge 

 of r ad ul a). 



Genitalia having a very short vestibule ; lower part of vagina 

 swollen, enlarging again above as it passes into the spermatheca 

 duct. This duct is very long, slender and closely bound to the uterus 

 above, ending in a globular receptacle. Below, the lower portion of 

 the duct is very large, with muscular walls, and bears a short blind 

 sack, directed downwards. This sack, and the enlarged duct and 

 vagina together, have strongly ridged internal walls. Uterus hav- 

 ing a very narrow neck (pi. 47, fig. 5, showing neck of uterus and 

 its union with vas deferens, below the blind sack of spermatheca 

 duct). Ovo-testis composed of a very long, straggling series of irreg- 

 ular clusters of fine follicles, imbedded in the liver along its inner 

 surface. The penis has the vas deferens inserted below the apex, 

 above and opposite to the insertion of the retractor muscle, which is 

 very long, and attached distally far back on the lung floor. Penis 

 cavity closely and strongly ribbed longitudinally, with no papilla. 

 Vas deferens firmly bound to the penis its entire length, and also firmly 

 bound to the vagina PI. 47, fig. 8, showing course of v. d. on penis.

Anoglypta is a monotypic genus created for one of the most 

 peculiar of all Helices. In its coarse spirally lirate-tuberculate 

 sculpture A. launcestonensis stands unique; and our knowledge of
