NOTES AND COMMENTS. 



VARIETY OF PALUDESTRINA J EN KIN SI. 



In the recently-issued 'Journal of Malacology,''''' Mr. H. 

 Overton describes a variety of Paludestrina jenkinsi, to which 

 he gives the name aciileata var. nov. It was collected along 

 W'ith others of the keeled form, from the canal at Muckley 

 Corner, near Wall, Staffordshire. As will be seen from the 



Paludestrina jenkinsi var. aculeata. 



figure, kindly lent to us by the editor of the journal, there is 

 a number of minute spikes irregularly distributed around the 

 keel of the different whorls. In other respects the shell is 

 typical. ■ We should be glad to hear of records of this variety 

 elsewhere. 



MOLLUSCAN MIXES. 



In the t8 pages comprising the same issue of the 'Journal 

 of Malacology,' 15 are occupied by four articles describing no 

 fewer than 49 new^ species of shells and one new variety. Then 

 follows a note drawing attention to the fact that ' Several pre- 

 occupied generic names have lately been proposed,' etc. ! In 

 the description of one 'new species,' rejoicing in the name of 

 D Lplommatina {Nicidd) delectahilis , reference to a Fig. 41, 

 Plate ii., is given, though w^e cannot find Fig. 41 on any of the 

 plates in the publication. Judging from the length and nature 

 of some of those proposed, it w^ould almost appear that our 

 conchological friends are experiencing difficulty in finding new 

 names, e.g., cyrtochila, serendibensis , gaylordce , brunneolineata , 

 briumeqflavida, piirpzireoapicta, siiavissiina, and, exasperata ! 

 Another conchological publication, 'The Nautilus,' for the same 

 month as the above-mentioned journal, contains 12 pages, which 

 include the following items : — New species of Viviparidcc and 

 Unionid(B from Florida, A new species of Mediotu'dus, A new
