MOLLUSCA OP INDIA. 37 



(The sole of the foot very closely segmented.) I have been successful 

 iu getting out the genitalia, but in a detached state. The specimen 

 contained 8 well-formed eggs in the oviduct ; they measure 1-5 mm. 

 in diameter, perfect globes. The penis (Plate CLXV. fig. 6) 

 has an elongate simple sheath, with a very small flagellum, close 

 to the vas deferens attachment at the distal end. The spermatheca 

 (fig. 6 a) was elongate with a bulbous end ; the penis is thus similar 

 to that of O. lonrjispira of Sikhim, and it may ultimately be found 

 that all the elongate turreted Glessul(p. will have this type of male 

 organ distinguishing them from that of G. ochracea, &c. The 

 formula of the radula is : 



20 . 7 . 1 . 7 . 20 or 27 . 1 . 27. 



The centre tooth has a long narrow plate with a small cusp at the 

 base ; the admedian are of the same shape as in G. longispira ; the 

 marginals are very numerous, becoming very minute on the outer 

 edge. There are no intermediate teeth ; the admedian merge into 

 the marginals. 



Glessula stjbhastttla, n. sp. (Plate CLXI. fig. 18; Plate 

 CLXIII. fig. 15, apex.) 



Locality. Nongsingriang, North Khasi Hills ; No. 3551 B.M. 

 T3'pe (Godwin- Austnit'). 



Shell elongately ■conoid ; sculpture irregular, fine close, very well- 

 defined transverse stiiation (not so regular as in G. hastula) ; 

 colour dark oehraceous ; spire long attenuate (less so than hastula), 

 apex fine (larger than in hastula) ; suture impressed ; whorls 7^, 

 sides flatly convex ; aperture very narrow, vertical ; peristome 

 thin ; columellar margin nearly straight. 



Size: Type. Maj. diam. 3-25; length 9'0 mm. apex. 

 N. Khasi sp. (3546' b!m.) „ 3-5 „ 10-75 „ 



largest (3557 B.M.) „ 3-50 „ 12-0 „ 



I first found this species (No. 3549 B.M., enlarged apex, 

 PI. CLXIII. fig. 14), which I then took to be hastula of Benson, in 

 the deep valley to the east of Cherra Poonjoe the first summer I 

 passed there. Two specimens were returned to me by Mr. Sylvanus 

 Hanley, in whose hands I placed a number of species of Glessula 

 when he was working on the ' Conohologia Indica' — this No. 3546' 

 (PI. CLXI. fig. 19) was returned to me with a note in pencil 

 " allied to sublvsiforiiiis, W. BIf ." A single specimen of suLhastula 

 was also found in the Dunsiri Valley below SMmagutiiig. 



I have received a specimen from Mr. S. W. Kemp found at Tura, 

 Garo Hills. 



Glessula sfbrastula, G.-A., var. type (Plate CLXI. fig. 19.) 



Locality. North Khasi ; No. 3546 (Oodwin-Austen). 



Shell elongately conoid ; sculpture regular, quite strong striation ; 

 colour rich umber-brown : spire long, sides Hattened, apex blunt 

 rounded; suture impressed; whorls 7|, sides flattened ; aperture 

 rather narrow ; peristome slightly thickened ; columellar margin 

 nearly vertical, not truncated.
