each whorl, from below the embryonic whorl two of these appear 

 on each succeeding whorl, weaker than these a third one lies just 

 above the suture and runs out on the last whorl at the corner of 

 the mouth nearly as strong as the other two : on the base a 

 similar but weaker keel encircles the pillar. These keels are parted 

 by a flat shallow furrow, which is rather over "001 in. in width, and 

 which is scored across by pretty close-set distinct but not strong 

 round-topped longitudinal threads, which again are scoredby micro- 

 scopic spiralstrise ; these striae,but hardly the longitudinal threads, 

 are visible on the top of the spiral keels. Colour white, glossy, but 

 hardly brilliant. Spire high and narrow, with a blunt, globular, 

 regular, one-sided, hyaline, glossy tip, consisting of one whorl on 

 which some very faint longitudinal striae are doubtfully traceable. 

 Whorls 6, with a contour very much angulated by the spiral 

 keels and the broad sunken suture. Suture is wide, deep, and 

 rather oblique. Mouth obovate, rather large. Outer lip has a 

 sweep which in itself regular is much disturbed, especially on 

 the base, by the spiral keels and furrows, these give the thin lip- 

 edge an unfinished appearance. Inner lip somewhat irregular, 

 from the forward tip to the umbilicus it is patulous and slightly 

 curved ; where it strikes the base the curve is obtusely and 

 roundly angulated ; across the body the lip runs in an oblique 

 straight line with a projecting strongish edge till past the um- 

 bilicus, when it lies close back on the body and though thinner 

 continues till it joins the outer lip. Umbilicus is a deep narrow 

 chink.— L. 008." B. 0-035. 



This species I found sparingly (some 25 specimens) at the 

 Gorgulho shore, and in deeper water at Punta de Sao Lourenco. 

 It is the unnamed " rare " species which Mc Andrew gives 

 (Geog. Distrib. p. 32) as dredged by him in 12 fms. at Orotava, 

 Tenerife, and specimens of which are in his collection. At first 

 sight the shell is startlingly like the Hydrobia bicarinata, des 

 Moulins, from the South of France, but the differences are very 

 marked.
