Martyn's Universal Conchologt — In the course of his very 

 instructive paper on " Thomas Martyn and the Universal Concholo- 

 gist," in the Proc. U. S. N. M., xxix, 1905, Dr. William H. Dall 

 writes as follows (p. 425), " I am not aware of any other copies of the 

 " Universal Conchologist " in America than the one I have described 

 [a copy in the U. S. National Museum comprising the first eighty 

 plates] and a similar copy in the Academy of Natural Sciences, 

 Philadelphia. Later in his " Supplementary Notes, etc.," in the 

 same Proceedings, vol. xxxiii, 1907, p. 185, Dr. Dall describes a 

 third copy in the possession of Mr. John B. Henderson, Jr., of Wash- 

 ington, likewise consisting of eighty plates, " elegantly bound." 



It may be of interest to readers of The Nautilus, especially those 

 residing on the Pacific Coast, to know that there is a fourth copy of 

 this rare work in the library of the Leland Stanford Junior University. 

 This copy comprises all four volumes of the work, including beautiful 

 impressions of the entire 161 plates, and is complete save for the ex- 

 planatory table for the plates of the third volume. The series was 

 the gift of Mr. Timothy Hopkins, and in this case, also, each volume 

 is " elegantly bound." A copy of the prospectus of the work, simi- 

 lar to the one described by Dr. Dall is laid into the first volume. 

 Beyond this the copy agrees very well with those already described 

 by Dr. Dall. S. S. Berry. 



Helix arbustorum var. roseolabiata. — The var. roseolabi- 

 ata, described as new by Mr. Schlesh in Nautilus, October, p. 55, 

 is var. roseolabiata Roberts, described from the British Islands many 

 years ago. T. D. A. Cockerell. 



Mr. J. H. Ferriss, who has been getting snails, ferns and health 

 in the Chiricahua range, Arizona, expects to return about Novem- 

 ber 15th. He has not yet turned up the multicorm's — a shell re- 

 ported to be as big as a tin-cup, with horns — but he has found many 

 other good things.
