THE NAUTILUS. 



LIST OF MARINE SHELLS COLLECTED AT PORT GUEYDON, KABYLIA. 

 WITH DESCRIPTION OF A NEW CYCLOSTREMA. 



BY C. F. ANCEY. 



The following is a list of marine shells mostly collected by the 

 writer during a part of the summer of 1895. A few not personally 

 collected are also included here and these are marked with an 

 asterisk. Much attention has been paid to the minute shells ; thus 

 the larger and less interesting ones have been somewhat neglected, 

 and there is but little doubt that some, not rare indeed on the North 

 African shores, are also to be found at Port Gueydon. This is not 

 so good a locality for collecting as many other places visited by me, 

 but as no list of marine shells of Kabylia has hitherto been published 

 I thought the present one should be useful ; moreover I discovered 

 here some little known or very rare forms, two of which at least I 

 consider as new. 



Murex Irunculus Lin. One spec- 

 imen is unusually large and 

 has an orange-tinged aperture.
