SMITH : SOUTH AFRICAN MARINE SHELLS, WITH NEW SPECIES. 109 



The Sigaretus tongamis of Quoy and Gaimard and the Coriocella 

 7iigra of Blainville are probably identical with this species. 



The shell from South Africa is of ioterest on account of its very 

 large size, the diameter of the body whorl being 50 mm., whereas in 

 ordinary examples it is only about 30-36.. It is also rather thicker 

 and more solid than usual, probably the result of age, and is covered 

 with a thin deciduous pale straw coloured periostracum. 



12, Eulima translucida (PI. I., fig n). 



Testa miniita, l? rev iter obtuse subulata, pellucida^ vitrea, poUta ; anfr ac- 

 tus sex, primus magnus^ rotundatus, sequentes fere plant, ultitnus ad 

 latera leviter curvatus, mediocriter elongatus ; apertura elongate 

 piriformis ; peristoma lev is si me incrassatum, niargine columellari 

 anguste refiexo. Longit 2\ mm., diam. |. Apertura J lojiga, h lata. 

 Hab., East London, Cape Colony (Miss M. Lavertine). 

 A very minute slender shell, but rather obtuse at the apex, and so 



transparent that the columella is visible to the apex. 



13. Eulima algoensis. (PI. I., fig. 10). 



Testa parva, alba, polita, infra suturam zona pellucida angusta 

 instructa, subulata, leviter curvata ; aiifr actus 12? leviter convexi, 

 sensim accrescentes, sutura levissime obliqua se/u?icti, ultimus ad peri- 

 pheriam rotundus ; apertura piriponnis, longit. totius \ hand 

 cequajis ; labruin arcuatum, in medio promitiens ; co'uniella leviter 

 iticrassata et refexa, superne callo tenui labro juiicta. Longit. 8 ///;//., 

 diam. 2. Apertura i^ longa, i lata. 

 Hab., Algoa Bay, Cape Colony. 

 Allied to E. atlantica Smith, but having more convex whorls, with 



a narrower pellucid zone below the suture. It also has a different 



curve in the whole length, and is more clavate in its general form. 



Both of the specimens examined have lost the apex, and consist of 



only eight whorls. 



14- Scala millecostata Pease. (PI. I., fig 5). 

 Scalaria millecostata Pease, Proc. Zool. Soc, i860, p. 400. 



Hab., Sandwich Islands (Pease); Isipingo, Natal (H. Burnup). 



Two specimens from the latter locality seem to be inseparable from 

 this species, of which I have seen only a single speciuien (the type) 

 from the Hawaiian Islands. They have the thread-like riblets even 

 more crowded, there being as many as forty on the last whorl. They 

 are slender, oblique, and so much reflexed that they really become 

 almost hollow tubes. The normal whorls are eight in number, very 

 convex, and exhibit between the riblets spiral striae which, however, 

 are only seen when the reflexed portions of the riblets are broken 

 away. Length 9 mm., diam. 6^ ; Aperture 3 long, 2^ wide.
