128 LAND AND FRESHWATER 



subspecies of AriopJmnta cysts under the title of A. dalyi, sent by 

 Mr. W. M. Daly from the Kadur district, Mysore. He kindly handed 

 me the animal for examination, and I am now enabled to give a 

 figure of the genitalia, the very brief account of which appears 

 in the above paper. I copy his description of the shell : — 



"Ariophanta dalyi, W. T. B., subspecies. {A. cysis, var.) 

 (Plate XCVIII. fig. 4.) 



" Testa sinistrorsa, umhilicata, depresso-glohosa, tenuis^ oblique 

 striata, fusco-cornea, fascia pallide ad peripheriam circumdata, 

 subtus juxta umbilicum pallido-cornea ; spira convexo-conoidea, apice 

 obtuso, sutura impiressa; an.fr. 5 convcvinscidi, idtimus non descendens, 

 ad peripheriain obtuse angulatus, antice latior, superne plamdatus, 

 subtus tuviidus, nitidus ; apertura ampla, diagoncdis, oblonyo-ovata, 

 vix lunata, margine superiori recto ; perist. album, interdum roseo- 

 tinctwn, margine superiori vix, dextrali basaJique expansiusculis, 

 columellari rejlexo. 



" Diam. maj. 39, min. 31 ; alt. 22 mm. 



" Hab. Balur, province of Kadur, Mysore. 



" This form dift'ers from typical A. cysis by having a higher spire, 

 by the last whorl being subangulate at the periphery, b}' its darker 

 colour, and by the whitish band round the last whorl. The mouth, 

 too, is differently shaped, owing to the upper margin in A. dalyi 

 being straight, not curved. The spiral striation of A. thryseus is 

 completely wanting, as it is also in typical A. cysis. The form of 

 A. cysis&gured in the ' Conchologia Indica,' pi. xxv. fig. 5, and said 

 by Hanley {t. c, Systematic List of Species, p. vii, footnote) to be the 

 variety named Helix anipidlaroides by Reeve, approaches more 

 nearly to A. dcdyi than any other described race, but differs con- 

 siderably. From A. intamescens the present form may be at once 

 distinguished by its more depressed form, much wider umbilicus, 

 and differently shaped mouth." 



Animal. The left neck-lobes are separated into two parts. 



The genitalia (fig. 4). The male organ is much simpler than in 

 A. Icevipes, although of the same type. The retractor muscle is given 

 off from a stout long ctecum {crp) continuous with the main sheath 

 below. At the junction of these two parts is the kalk-sac, on a 

 very short tube which the vas deferens joins. It is thus strikingly- 

 similar to the same part in Batnadvipia (Plate LXXXV. fig. 6). 



The spermatheca is very short and oval in shape ; the amatorial 

 organ short and stout. At the head of the vagina, above the junc- 

 tion of the spermatheca, is an enlargement of the main duct 

 (fig. 4, ot), a glandular caecum, Avhich is also present in A. Icevipes. 



The odontophore is nearest to A. cysis and A. immerita {vide 

 Plate LXXXII. figs. 6-6 c, 7-7 o), arranged thus : — 



-h30 . 3 . 17 . 1 . 17 . 3 . 30-1- 

 -f50 . 1 . 50-f- 



The salivary gland is very broad and spread out in a thin film over 

 the surface of the stomach.
