 Dosinca joinislmii, Tate.

 p. 161, pi. XIV. Figs. 9 and 12. 



A mould of a shell of a Dosinea in white limestone shows by a 

 wax squeeze the characteristic costation of the alx)ve species. The- 

 concentric ridges measure 20 in a breadth of 10 mm. and are ele- 

 vated rather than depressed and rolled over to become almost con- 

 fluent, as in D. densilineata , Pritchard.^ The length of the present 

 example, if complete, would measure a]x)ut 50 mm. D. johnstoui 

 has a long vertical range, from Balcombian to Kalimnan (Balcombe 

 Bay, Table Cape, Upper Muddy Creek).
