I90 M. M. SCHEPMAN, LAND- AND FRESMWATER MOLLUSCA ETC. 



moderately long. Aperture roundedly-ovate, with a sharp angle above, forming a sort of canal, 

 peristome angular at the projecting ends of the keels, especially at the upper one, crenulated 

 by the lirae, columella much rubbed by a hermit-crab, consequently not describable, interior 

 of aperture grooved, in accordance with the keels. No umbilicus. 



Alt. 32, lat. about 19, apert. ait. (with canal) 16, lat. about 7 mill. 



New Guinea. Merauke, 1904. (Dr. Koch leg.') 



A very puzzling shell; by the lacking of the columella, I could not ascertain its generic 

 position, but the rest of the characters, made me locate it provisionally in the genus Cymia, 

 the shell was too peculiar to neglect it. 



Murex Linné. 



1. Murex brevispina Lamarck.

One spécimen agrées rather well with Tryon's figure, the other has a higher spire and 

 longer spines, in this respect intermediate between that figure (copied from Reeve, Conch. 

 le.) and M. senilis Jouss., which TRYON considers to be a long-spined variety. In the figures 

 of KlENER and KOBELT in their monographs of Murex, the shells hâve a flatter spire and 

 shorter spines. 



2. Murex sp. 



New Guinea. Merauke, 1904. (Dr. Koch leg.) 



Two spécimens are too bad to be identified ; they resemble M. martinianus Rve. but 

 hâve less developed traces of vertical ribs between the varices and the spines are longer than 

 is commonly the case in that species. 



3. Murex permaestes Hedley.

New Guinea. Mimika, March 10, 1909. 



This is the common species mainly called M. capucinus Lam., but Hedley after in- 

 specting the type in the Muséum at Geneva, has observed that it was quite another shell: 

 „perhaps related to M. torrefactus Sow. or Purpura tubulata Martyn". Setting apart the 

 possibility that the type of LAMARCK has been changed, I hâve accepted, though with 

 resrret, his views.
