106 ME. E. A. SMITH ON L.UTD-SHELLS FEOM [Feb. 5, 



Var. PALLIDA. Testa typo minor, dilute fiisco-cornea. Diam. 

 maj. 16 milUm,, min. 14, alt. 6. 



The variety, which was collected at the same locality as the type, 

 consists of the same number of whorls, is similarly sculptured, and 

 has a similar aperture and peristome. With the exception of its 

 small size and paler colour, it agrees perfectly with the typical 

 form. The colour of the latter is a rich purplish red-chestnut 

 above and helow. The extreme edge of the keel and the suture are 

 pale, and above and beneath the keel and above the suture a 

 narrow dark spiral line is observable. It differs from T. alexis in 

 colour, the greater width of the whorls, and the much stronger 

 spiral sculpture. 



15. Teochonanina whiteheadi. (Plate 11. figs. 17, 18.) 

 Testa parva, T. paraguensi similis, sed minor, carina acutiore, 



labia magis sinuoso.

 Hab. xs". Borneo (/. Whitehead). 



This is the smallest of the known Borneau forms. It has aU 

 the general characters of T. paraguoisis, but may be separated on 

 account of certain slight differences, such as the sharper more 

 compressed keel, somewhat paler colour, and more sinuous basal 

 lip. 



Eteeettia, Godwin-Austen. 



Nearly all of the species of this genus are exceedingly difficult 

 to distinguish by their shells, and it is quite impossible to determine 

 them from the published descriptions or even the figures. The 

 slightest inaccuracy in outhue gives to a figure quite a different 

 appearance from the specimen delineated. It is only by comparison 

 of the type examples that we can determine the species with any 

 degree of certainty, and even under these favourable circumstances 

 it IS a task of no mean difficulty. With the exception of E.htjalina 

 (Martens), the types of all the known species from Borneo are in 

 the British Museum, and consequently the determination of a 

 number of forms from that island, acquired within the last two or 

 three years, is to a great extent facilitated. E. bochi, quoted by 

 Grodwin-Austen^ as of Issel, is purely imaginary, and is not 

 described at the reference given.

 perforata, nitidissima, s^ipra et infra tenuissime spiraliter 

 striata, lineisque incrementi ohliquis infra snturam confertim

 accrescentes, idtinuis rotundatus, infra in medio iinpressus; 

 apertura oblique limata, intus opalescens ; peristoma tenuissi- 

 mum, margine columellari leviier incrassato, ad, insertionem
