I5LANF0KD : NOTES ON A1UOPHANTA AND EUPLECTA. 249 



This is distinguished from typical A. thyreus (Bs.), by being less 

 depressed and thinner, and more narrowly umbilicated, the suture is 

 deeper near the mouth, the last whorl is more tumid beneath and less 

 annulate at the periphery, and the sculpture is not decussated. The 

 colour is paler, and the reddish band below the periphery is very 

 distinct. 



A. ryssolemma (Albers), as figured in Pfeiffer's "Novitates Concho- 

 logicre," vol. i, p. 37, pi. x, figs. 13, 14, evidently froma weathered 

 specimen, is another form of A. thyreus deserving of a distinctive 

 name, and which I class as a subspecies. My own specimens were 

 obtained, like those of A. hetercea, at Sispara Ghat. They have strongly 

 decussated sculpture, and are much larger than typical thyreus, 

 measuring maj. diam. 40, min. 33, axis 20 mm. (the type of A. thyrem 

 was 34 mm. in major diameter). 



A. hetercea is intermediate between A. thyreus and A. cysis, and 

 has some claim to be regarded as a distinct specific form. 



3. ApaorHANTA (Xestina) Gassii, n.sp. PI. XXV, Fig. 3. 



Testa subobtccte perforata, depresso-globosa, tenuis, rugato-striata, 

 supeme fulva vel dilute castanea, subtus pallidior, zona castanea 

 angusta supraperipherali ornata ; spira parum elevata, conoideo- 

 convexa, sutura impressa; anfr. 6 convexi, ultimus latior, hand 

 descendens, ad peripheriam subangulatus, subtus convexus ; apertura 

 obliqua, lunato - subovalis ; peristoma obtusum, album, margine 

 columellari obliquo, juxta perforationem abrupte atque sublate 

 reflexo, perforationem partim tegente. Diam. maj. 36, min. 29, 

 axis 21 mm. 



Hob. — In montibus Animalai et Pulney dictis, ad latus occidentale 

 Peninsulae Indica3 haud procul a littore Malabarico, necnon in provincia 

 Travancore (Beddome). 



This is distinguished from A. Maderaspatana by rather larger size, 

 narrower perforation, generally darker and more uniform coloration, 

 and especially by the columellar margin of the peristome as shown on 

 PI. XXV, Figs. 3 and 4. In A. Maderaspatana the columellar margin 

 is slightly expanded throughout, the amount of expansion increasing 

 gradually above, and the terminal portion being carried forward, 

 whilst in A. Gassii there is scarcely any expansion till close to the 

 perforation, where the margin is abruptly reflexed. 



4. Euplecta teansfretata {E. semidecussata n.subsp.). 

 PI. XXV, Fig. 9. 

 Testa subobtecte perforata, depresso-turbinata, castanea, rugato- 

 striata, lineis impressis spiralibus decussata, subtus ltevior, solum 

 extus decussata ; spira conoidea, apice acuto, sutura impressa ; anfr. 7 

 lente accrescentes, convexiusculi, ultimus non descendens, ad peri- 

 pheriam angulatus, subtus convexior ; apertura obliqua, angulato- 

 lunaris, fere semiovalis ; peristoma tenue, rectum, margine columellari 

 breviter reflexo, perforationem fere tegente. Diam. maj. 30, min. 27, 

 axis 18 mm.
