GUDE t SPECIES OF PLECTOPYLIS. 



With a number of Pledopylis kindly sent to me by Colonel 

 Beddome for inspection, were three shells which he thought would

prove to be new. Upon examination I found them to differ from all 

 the described species, and now, therefore, publish this form as a new 

 species under the above name, which was suggested by Colonel 

 Beddome. Pledopylis mtispratti in outward appearance somewhat 

 resembles Pledopylis nagaeiisis ("Science Gossip," N.S., vol. iii, p. 

 206, fig. -XfT^, but the armature is quite different. The parietal 

 armature (see figs, e and d) consists of a strong, vertical lunate plate, 

 strongly deflected posteriorly below, the convex side towards the 

 aperture ; below, on the anterior side, is a very short horizontal fold ; 

 a short, entering, flexuous, horizontal fold occurs at the aperture and 

 is joined to the flexuous raised ridge which unites the two niargins of 

 the peristome. The palatal armature consists of: first, a free, short, 

 horizontal fold with a small denticle posteriorly ; next, four short, 

 horizontal folds connected by a slight vertical ridge about their 

 middle ; the posterior halves of the folds being thinner and slighter 

 than the anterior halves; the vertical ridge is continued below the 

 fifth fold, where it suddenly deflects posteriorly and terminates in a 

 small oblique denticle ; below the fifth fold, a little nearer to the 

 aperture, is found a sixth fold, which, like the first, is quite free (see 

 fig. 5^ which shows the inner side of part of the outer wall with its 

 palatal folds, and fig. 5^, which gives the posterior view of the parietal 

 and palatal armatures). — "Science Gossip," iv, p. 10.
