THE NAUTILUS. 103 
Custer Co. I doubt whether minutissima is separable even as a 
variety from pygmea. 
P. (Punctum) conspecta (Bland.) San Juan Co. (Ingersoll). 
P. (Thysanophora) ingersolli (Bland). San Juan Co. (Inger- 
soll); near Brush Creek, 10,000 ft., Custer Co. ; Clearwater Creek, 
Grand Mesa, Mesa Co. A species of high altitudes. 
P. (Helicodiseus) lineata (Say). Animas Valley (Ingersoll). 
Helix (Stenotrema) monodon Rack. Colorado Springs (Yarrow). 
Beyond this record, nothing is known of any species of the group 
in Colorado. Probably the Colorado Springs H. monodon was 
introduced by human agency. 
H. (Vallonia) pulchella var. costata (Mull.) San Juan Co. 
(Ingersoll) ; South Park (Yarrow); Micawber Mine, Custer Co. ; 
Rock Creek, Routt Co.; Kremmling, Grand Co.; Pueblo Co.; near 
Salida, Chaffee Co.; Black Lake Creek, Summit Co.; Buzzard 
Creek, Mesa Co.; near Cattle Creek, Garfield Co. Perhaps costata 
deserves to rank as a species distinct from pulchella. 
HI. pulchella costata form cyclophorella (Ancey). The ribs in 
this form are close and delicate, but it seems to me referable to 
costata. Mr. Ancey has identified a specimen from West Mountain 
Valley as cyclophorella, and indeed, if the name is to be adopted, it 
will probably include at least a majority if not all of the Colorado 
specimens of Vallonia. Vide 11th Rept. Colo. Biol. Assn. (1889). 
H. pulcnella pulchella Mill. Binney records pulchella from Este’s 
Park, but it is probable that the form was costata. 
West Cliff, Custer Oo., Colorado, Dec. 10, 1889. 
AN ANNOTATED LIST OF THE SHELLS OF ST. AUGUSTINE, FLA. 
BY C. W. JOHNSON. 
The following is a list of the shells which came under my observa- 
tion while living at St. Augustine from 1881-88. 
As very little dredging was done it is probably far from complete, 
but as some of the notes may be of interest to the Conchologist, I 
herewith submit it to the readers of the Nautilus.
