Amoxg a quantity of small shells recently submitted to me for 

 identification from the Kowie and Pondoland by Dr. H. Becker, of 

 Grahamstown, the following are worthy of attention : — 



SlPHONARIA CYANEOMACDLATA, D.Sp. 



Testa ovato-oblonga, subdepi-essa, fusca, albo radiata, maculis parvis 

 numerosis cyaneis picta, ubique cont'ertiss-ime radiatim striata, con- 

 centiice rugata ; latiis dextruui latiusculura, radiatim qiiadricostatum, 

 costis albidis; sinistrum angustiiis, contractuni, eostismajis numerosis; 



vertex sinistro'rsum inclinatus ; pagina interna centralis albida, versus 

 niarginem uigro-fusca, albo radiata, ad marginem dentata. Long. 15, 

 lat. 10, alt. 4 mm. 



Sab. — The Kowie.

 form of the shell is not an uncommon one in the genus. In describing 

 it as having four ribs on the right-hand side, I must remark that 

 there are signs of intermediate ones> which in other specimens may 

 be more fully developed. 



Terebra FiLMEK^, n.sp. 



Testa elongata, pallidissime fulvai ; spira vix convexiuscula ; an- 

 fractus IH, apicales Ifeves, tertius planatus, longitudinaliter leviter 

 plicatus, dcinde Cccteri supra medium obtuse angulati, plicis confertis
