(leeches etc.,) 7 and one variety; Nemato- 
scolices, 1. There are also many species 
which have long ago become extinct, and 
their fossil remains now attest their for- 
mer existence; of fossils we have records 
of 77 Mammals; one bird; 28 Reptiles; 
2 Fishes; 25Mollusca; 2Homoptera; and 
one each of Cole^ptera, Neuroptera, Hy- 
menoptera, O^thoptera,' Rhopalocera, 
Diptera and Echinodermata. 
The plants recorded in our books for 
Colorado are also very numerous, name- 
ly Flowering plants, 1370 and 164 varie- 
ties; Gymnosperms (pines, firs etc.,) 15 
and 2 varieties; Ferns and their allies, 
32 and one variety; Mosses, 112 and 8 
varieties; Hepaticae (liverworts,) 15; 
Fungi, 70 and one variety; Liijichens, 65 
and two varieties; Algae, 31. We have 
also records of several kinds of fossil 
plants: Flowering plants, 124 and 4 va- 
rieties; Gymnosperms, 6; Pteridophyta 
and Characeae, 23; Algae, 4; and Fungi, 1. 
Mr. C. F. Ancey has examined some 
snails which we collected in western Cus- 
ter county, and sends us his notes on 
them. One species of Pupa he says ap- 
pears to be P. hebes, and another is what 
he has recently described as P. ingersolli. 
Specimens of Vallonia he considers to be- 
long to an undescribed species, which he 
calls cyclophorella, but we prefer to con- 
sider them a form of costata at present. 
Examples of Physa, which we shall call 
P. heterostropha var. heterostrophella, 
he thinks probably represent a new spe- 
cies. They were found at Westcliffe.
