. REPORT ON THE GASTEROPODA. 149 



Habitat. — Indian Ocean and Moluccas (Chemnitz), Torres Straits, Darnley Island, 

 20 to 30 fathoms (Brazier). 



The embryonic apex consists of nearly two faintly yellowish-white, almost equal, rounded whorls, 

 the second of which has a strong central carina.

 Habitat. — Eed Sea, China, Philippines (Kiener). 



The embryonic apex consists of two glossy, brown whorls. The second is no higher nor broader 

 than the first, which has its extreme point a little inverted and bent down on one side. The hollow 

 spines appear on the spire before the end of the third (or first ordinary) whorl. 



In citing authorities above, I have given Tryon's figures as he gives them, though obviously he 

 has confounded several species. It were much to be wished that, before mixing up species, authors 

 would ascertain that they really have the species they discuss. In many museums the confusion in 

 this group is extreme. In the fine collection of the Public Museum at Liverpool, which is under so 

 efficient a keeper as Mr Marrat, I wasted much labour over this group, only to reach the conviction 

 that the species were not well identified. 



I have not quoted Kiener, Iconog., p. 6, No. 3, pi. viii. fig. 1, and pi. ix. fig. 1, because his 

 Murex ternispina is not this species, but the Murex crassispina, Lam. 



In the British Museum there is a species which closely approaches the Murex ternispina, Lam. 

 It is named Murex Eecvianus, Shuttleworth ; but I have not been able to trace its history, and 

 possibly it never has been published. Mr Shuttleworth knew shells too well to be lightly charged 

 with error ; but is the species a good one ? The embryonic apex of the specimens in the British 

 Museum seemed to me different from those of Murex ternispina, Lam., but in all they have been so 

 much eroded with acid that certainty, there at least, was impossible.
