THE NAUTILUS. 9 
orado, by the Grand River, in Garfield Co., and by Plateau Creek, 
in Mesa Co.; e. trifasciata, with three bands, one above the periphery 
and two below, all distinct, the area between the first band and the 
suture marbled with brown, Mam Mountains, Mesa Co., Colorado ; 
f. alba, white with rough strive, Utah (Hemphill). Hemphill also 
mentions a white variety of Patula strigosa, Gld., from Utah, which 
may be called var. alba. 
I have recently found Cochlicopa lubrica and Hyalina radiatula 
near here. Also Limnea truncatula and two species of small 
Pupe, which may be new. Theo. D. A. Cockerell, West Cliff, Col. 
On the occurrence of Limosina in Texas. According to Prime, 
the species of this group are “widely and abundantly distributed 
through Central and South America and the West Indies,” to the 
exclusion of the equally abundant species of Sphawrium peculiar to 
the United States. Several years ago Mr. G. C. Heron sent me three 
specimens of a Spherium from Cedar Creek, Hudson Co., Texas, 
whose unusual shape and mottled epidermis at once struck me as 
peculiar. On sending one of the specimens directly to Mr. H. A. 
Pilsbry, of the Philadeiphia Academy of Natural Sciences, for iden- 
tification, I was informed that he could not satisfactorily identify it 
with any known species, but that it was nearer to J. cubense Prime, 
than to anything else, although for the present the specific identity 
of the specimen must remain uncertain. ‘Fhe occurrence of this 
group, hitherto unknown to our fauna within the United States, 
would seem to be a fact worthy of record. Bryant Walker, Detroit,

H. (Fruticicola) similaris, Fer., Triodopsis appressa, Say, Sten- 
ogyra decollata, L., in Bermuda. All three have been probably in- 
troduced in the past 25 years. During a recent visit, I found the 
first mentioned near the Government house in Hamilton. The 
second species was shown me by Miss A. M. Peniston, of The Flatts, 
who secured it from Mr. Bartram. It occurs near St. Georges. 
The last species is so common it threatens to become injurious to the 
crops there. It was introduced with some European plants, and 
first made its appearance at Mt. Longdon. Stenogyra octona Chem., 
is also found upon the island, and is not mentioned by Bland. T. HN. 
Aldrich, Southern Ave., Cincinnati, Ohio. 
In the Western American Scientist for April, p. 8, Mr. Berlin H. 
Wright has described as new, under the name of Bulimulus hemp- 
hilli, the species figured by Binney (Manual N. A. Land Shells, fig. 
440) as a variety of B. floridanus. The form in question should be 
compared with B. marielinus Poey.
