Vermicularia caperata Tate & May. 



(Plate x., figs.37-38.) 



Some notes on this species have already appeared in these 

 Studies (vi., p.19) The protoconch, I find, consists of a small 

 brown semitransparent Rissoa-like shell of 2 \ whorls, 1*4 mm. 

 long. A sudden change in form and texture expresses the change 

 to adult life. The larva settles aperture downwards, shell pros- 

 trate. The first irregular adherent whorl encircles, then mounts 

 upon and buries the protoconch. Thus the first adult coil is at 

 right angles to the larval axis as in Turbonilla.

The locality of this species was unknown to Reeve, whose 

 name therefore escaped inclusion in Australian lists. The 

 synonym of Angas was preoccupied in Columbella by Carpenter, 

 Duclos and Dujardin. It was corrected or misreported in the 

 Zoological Record as " filamentosus." Tenison-Woods* noted 

 C.filosa to be a rare Tasmanian shell. Pritchard and Gatlifff 

 record it from Western Port. Brazier took a sinistral individual 

 in Sydney Harbour. J

Hanley has recorded§ the existence in the Linnean Collection 

 of two adult shells marked " Murex mancinella." These conform 

 to the original diagnosis, and must be regarded as types. But
