22. Crossea concinna, Angas, P. Z. S. 1867, pi. xliv. f. 14. 



The genus Crossea was founded by Mr. Arthur Adams for the 

 reception of two species from Japan. He remarks of these singular 

 and beautiful little shells, " they have perhaps the closest affinity 

 with Cirsotrema (Morch), a genus of Scalidce. They also remind 

 one of Torinia and Conradia. A great peculiarity consists in the 

 canaliculate angular projection at the fore part of the aperture." 



Dredged by Mr. Brazier near the "Sow and Pigs" reef, in Port 

 Jackson, at a depth of from 2 to 4 fathoms. 



23. Scala (Cirsotrema) morchi, Angas, P. Z. S. 1871, PI. I. 

 f. 7. 



Decussated with longitudinal ribs, and more numerous transverse 

 ridges ; the former evanescent at the base. 

 Dredged near the "Sow and Pigs" (Brazier).
