22. Z. fulvus, Drap. This species occurs here in limited numbers, 
at many localities. It presents no features of interest. 
23. Z. gularis, Say.—The typical form of this species occurs in 
abundance under leaves and about stones and logs everywhere at this 
locality. Many of the specimens are much elevated, and of compara- 
tively large size. An umbilicate variety occurs which is always more 
glabrous and more flattened. The variety which Dr. Lewis described as— 
24. Z. cuspidatus, also occurs abundantly. Of this form, Mr. Bland 
writes, “Ido not feel entirely satisfied that cusp¢datus is distinct.” It 
seems to me that the same treatment of the forms here included under 
one species, as has been given to the group embracing fuliginosus, 
capnodes, and friabilis, would give us two or three species instead of 
one. : 
But this is a question for the species makers to decide. 
25. Z. significans, Bland.—Shells which I referred at first to Z.-an- 
drewst, W. G. Binney, are undoubtedly Z, significans, Bland. They 
occurred with sculptilis and placentulus. 
26. Z. multidentatus, Binney.—This species occurs in the moss in 
small numbers. Some of the specimens approach, very closely, the 
previous one. 
27. Vitrinazonites latissima, Lewis.—This strange mollusk seems to 
be widely distributed over this region, and ranges from the foot of the 
Roan plateau, 2,800 feet, to 4,000 feet. It may occur higher, but this 
is as high as I found it. It lives among the leaves, in damp stations, 
or under them, on the ground, in dryer ones. It has the habit, so 
common among the species of Zonites, of spreading the foot out over 
the ground, and extruding a mass of mucus which attaches it, so that, 
even when the leaves are roughly raked away, the shell remains in its 
chosen piace. This character occurs with fuliginosus, capnodes, 
levigatus, subplanus, and friabilis. In excessively dry stations, on 
the top of the most barren spurs, these species will occasionally be 
found as stated above. The generic name given by Mr. Binney was 
especially well chosen, and there will doubtless be near allies of this 
remarkable form discovered in the near future. 
28. Patula alternata, Say.—A very beautiful, nearly smooth variety 
of this elegant species occurs here. No specimens of the variety 
mordax occurred. i 
29. Patula perspectiva, Say.—The normal type of this species occurs 
in limited numbers in the same stations as Z. elliottz. 
30. Patula bryanti, Harper.—This curious and rare new form was
