Type Bombay, probably also Ceylon and Andamans ; the specimens, 

 however, from these two Fast localities are not sufficiently perfect for satis- 

 factory identification. For the type specimens of this and for many other 

 interesting species from the same locality, the late Dr. Stoliczka was indebted 

 to the Rev. S. B. Fairbank.

Amongst some hundred specimens in the Museum from the Sandwich 

 I., Mauritius, Bourbon, Ceylon, and Abyssinia, a single Ceylon spe- 

 cimen alone shows minute denticulations just within the outer lip, as in 

 Reeve's figure. A comparison with specimens in the British Museum marked 

 interrupta, Rv. first enabled us to identify this species ; the genus still 

 seems to us doubtful, perhaps Carpenter (P. Z. S. 1865) is correct in placing 

 it in the Colwmhellidce. It is common in Ceylon, where it seems to be finer 

 and better marked than elsewhere in these seas. If it should prove to be 

 a pleurotomid, Pease's name bella had probably better be employed, as 

 Lamarck and Sowerby have both described distinct shells as JPleurotoma 

 interrupta.

 Pease is quite wrong (Am. J. Conch. 1871, p. 25) in uniting this 

 species with G. scalarina, Deshayes ; the short rounded whorls, more pro- 

 duced spire, different character of the sculpture, absence of the second black 

 transverse line on the whorls, amply distinguishing the latter ; the former is 

 abundant at Ceylon and Arakan, the latter at Mauritius, Bourbon, and 

 Ceylon.

This variety has 12 longitudinal ribs on the last whorl, four transverse 

 keels on the whorls, the two middle ones very prominent, the other two more 

 or less obsolete, suture excavated, only very faintly stained brown, minutely 

 and spirally striated ; two transverse brown lines on the last whorl, show- 

 ing also within the aperture ; it does not differ from the type form sent us 

 by Mr. Pease from the Sandwich I., as figured and described in the Don. 

 Bism., except by its greater size.
