134 THE NAUTILUS. 



so little labor for its installation. It is hoped that a man who 

 has so distinguished himself as an expert collector as Mr. John- 

 ston has in the past, will continue his conchological explora-

NOTE ON DIALA LEITHII SMITH. In the last number of the 

 "NAUTILUS" Dr. Dall calls attention to this species and con- 

 jectures that it may be a native of Lower California. 



There appears to have been some inexplicable confusion be- 

 tween Smith's paper on this species and the paper on Carinifex 

 ponsonbii which immediately precedes it in the P. Z. S. for 1875. 

 It is obvious that the figures in these two papers are transposed. 

 I have examined the type lot of D. lelth'd in the Brit. Mus. 

 (eleven shells and two opercula, reg. no. 75.6.17.1) and find 

 that it is labeled "Bombay Harbour, Dr. A. H. Leith." I 

 have no doubt that this is the correct locality, and I have in 

 my own collection a single example collected by the late Dr. 

 Archer at Singapore. J. R. LEB. TOMLIN. 



CYTHEREA VIRGINEA A. ADAMS AND REEVE. This species is 

 described and figured in the " Mollusca of the Voyage of H. M. 

 S. Samarang," p. 78, pi. 24, f. 10, and the locality given is 

 "Eastern Seas." The British Museum possesses the figured 

 type of this shell, received from the famous Lombe Taylor col- 

 lection, into which many of the "Samarang" treasures found 

 their way, as well as two other examples, and all three are juve- 

 nile specimens of Tivela stultorum Mawe. 



Hinds was probably responsible for the introduction of this 

 impostor amongst the Samarang' s collections. T. R. LEB.

LIMAX FLAVUS AT BAR HARBOR, MAINE. I found several 

 specimens of this slug in 1920, and again last year. C. W.

 described Lithasia plicata as from Green River, Jackson Co., Ky.
