forms of Achatina , but has rather the appearance of being 
obliquely plicate at the lower part. There is a slight film of 
callus connecting it with the upper end of the outer lip. The 
larger variety, like the type, has the faint raised line around 
the middle of the body-whorl, and agrees in all other respects 
except in the points above mentioned.

This fine species bears a general resemblance to S. rangi- 
ana , Pfr. (Reeve’s Conch. Icon., Achatina , fig. 65), but has 
longer whorls and is rather larger. An egg from one of the 
specimens is elongate- ovate and 5 millim. in length. 
Stenogyra ( Subulina ) usagarica. (PI. V. fig. 17.) 
Testa gracilis, subulata, nitida, albido-subpellucida, epidermide 
olivaceo-fusca plus minus induta; spira sursum attenuata, ad 
apicem obtusa ; anfract. 15, apicales pauci convexi, cseteri plani-

This is a very elongate species with almost flat whorls. 
The subplicate lines of growth, especially on some of the 
upper volutions, give the sutural line a somewhat crenulated 
appearance. S. Foxcrofti , Pfr., from Sierra Leone, has longer 
and more convex whorls and they are fewer in number. 
Stenogyra {Subulina) Lasti. (PI. V. fig. 18.)
