 was in course of publication.

I have suggested in These Proceedings (xxxi., p. 470) that G. 

 hoylei was a synonym of G. cardiiformis Angas. Comparing the 

 type of Angas, in the British Museum, with my shell from Mast 

 Head Island, I find them specifically different. G. cardiiformis has 

 a finer concentric sculpture, is more inflated, and has a more pro- 

 minent umbo than my Queensland shell. Dr. E. Lamy considers 

 that G. cardiiformis is the Californian G. multicostatus Sowerby.*

In the Lamarckian collection of the Geneva Museum, I noted the 

 types of this species, being four shells labelled in Lamarck's writ- 

 ing: "Modiola pulex nouv. hollande." Small initials were used by 

 Lamarck for place names. Subsequently M. Bedot kindly sent me 

 photographs and comparative notes. By their help, I can identify 

 Lamarck's species with M. crassus Ten. -Woods. This latter is gen- 

 erally, but I suggest improperly, united to M. confusa Angas. The 

 two have different stations, M. confusa occurring in sheltered 

 swamps, but M. pulex on exposed beaches. They also have a dif- 

 ferent contour. M. confusa is narrower in proportion to its length, 

 is broader at the umbonal end, is more inflated, and has a longer 

 hinge-line. Again M. pulex is bare, and M. confusa is meshed in a 

 byssus-web. In New Zealand, there is a corresponding pair of 

 species, M. ater Dunker and Zelebor, and M. fluviatilis Hutton.
