THE NAUTILUS. 
V, pp. 73, 283 (1807), for a genus of Rynchophorous Coleoptera. I 
therefore suggest as a new name for the Australian group Both- 
riembryon, the type being Bui. melo. — Pilsbry. 
Spirula peronii in Jamaica.—Mr. Edvv. W. Roper reports find¬ 
ing a specimen of this cephalopod containing the animal, during 
his recent visit to Jamaica. 
Mr. F. C. Baker has been appointed Curator of the zoological 
department of the Field Columbian Museum at Chicago. 
The collection of shells of the late Dr. Philip P. Carpenter is 
offered for sale. This is an excellent opportunity to obtain a val¬ 
uable and authoritatively named collection. Address Mrs. Minna 
M. Carpenter, 241 University St., Montreal, Canada. 
Some Arkansas Snails. —On my trip here (Fort Smith, Ark.,) 
I did what I did some years ago—walked from Winslow, on the top 
of the Boston Mountains, to Porter, six miles this side. I collected 
quite a number of shells, and will send you some living Triodo])sis 
edentcita, Stenotrema labrosum, Polygra Samjisoni and P. Jacks oni. 
I got the edentcita from the top of the mountain to Rudy, a vertical 
distance of 1500 feet. At the latter place they are found with the 
ordinary Triodopsis inflecta. I hope you will have time to examine 
the internal parts. I find that where I got the type specimens was 
in Washington County, instead of Crawford; but on this trip I 
gathered them in both counties.—F. A. Sampson, in letter. 
The Michigan Fish Commission has commenced an investiga¬ 
tion of biological conditions of the Great Lakes, with especial refer¬ 
ence to the life history of the white fish. The work will include a 
determination of the fauna and flora of Lake Michigan at Ann 
Arbor, and of their vertical and horizontal distribution. This de¬ 
termination will be both qualitative and quantitative, and will be 
particularly directed towards a study of the life history of the white 
fish and lake trout. Since the life of the w r ater constitutes first or 
last the food of the fish in it, this determination will afford some 
idea of the value of this locality as a breeding ground for fish and 
of its adaptability as a planting ground for the fry. The party at 
work in the laboratory will consist of various specialists, Mr. Bryant 
Walker, Detroit, Mich., taking charge of the mollusca.
