1 24 MITRELLA. 



A smooth shell, of simple growth, veiled, as it were, with a 

 very close network painting of dark chestnut. 



I reproduce Reeve's description and figure ; the type was in 

 the Taylor collection. It looks very much like a well-covered 

 specimen of C. cribraria. 



C. FLEXUOSA, Lam. PL 48, figs. 81, 82. 



Shell oblong, thick, smooth; whitish, with longitudinal chestnut- 

 colored, flexiious lines ; spire acuminated, volutions seven, (some- 

 times) furnished with a single row of small tubercles ; aperture 

 oblong-ovate, white within ; internal teeth of the outer lip few 



and distant. Length, 18 mill. 



Isle of France. 



This is a very doubtfully identified species. Sowerb}^ states 

 that the only specimen he has seen w r as obtained from the 

 Lamarckian collection by Mr. Cuming, and was tuberculated as 

 above described : on the other hand the specimen figured by 

 Kiener (fig. 81), as from the Lamarckian collection is smooth, and 

 differs in other respects from Sowerby's example. The figures 

 in Sowerby (fig. 82) and Reeve are so close to C. Australis, 

 Gaskoin, as to strongly indicate specific identity in which case, 

 Lamarck's species would, of course, have 



(!. EMARGINATA, Reeve. PL 48, fig. 84. 



Shell ovate, rat her stout, shining; whitish, banded mid blotched 

 with red-brown net work, spirally bilineated towards the apex; 

 spire rather short, sharp, whorls ribbed near the apex. then 

 smooth ; aperture small, lip conspicuously notched at the upper 

 part, strongly denticulated within. Length, 10 mi?l. 



This shell, in the Cumingian collection, is said to be like C. 

 /Hilch.eUa ( elegantula) but more solid and more strongly 

 colored, with a more than usual ema ruination of the lip. 



C. MICANS, Pease. PL 48, fig. 85. 



Shell smooth, polished, slightly striate at the base; spire- 

 whorls flattened, apex acute; light purple, under tine chestnut 

 streaks and reticulations, the sutures generally marked with a 

 row of narrow white lines ; aperture light purple within ; outer 



lip dentate.
