SAR TENG TON ETHNOZOOLOGY OF THE TEWA INDIANS 63 
there are perennial streams. Prof. T. D. A. Cockerell has a manu- 
seript list of New Mexico shells prepared by Rev. E. H. Ashmun, 
in which Pisidium is listed from Santa Fe. In El Rito de los Frijoles 
no aquatic shells were found, either bivalve or univalve. Indeed, 
the scarcity of aquatic animal life, except water beetles and ‘‘water 
boatmen,”’ may indicate that the water does not always flow in that 
rivulet in very dry seasons. The only record of an aquatic mollusk 
of any kind yet published is Physa, though Lymnea palustris Miller 
from Taos, and L. desidiosa Say (probably L. obrussa Say) and 
Planorbis parvus Say, both from Santa Fe, are included in Ashmun’s 
list. 
Land snails are usually to be found along the bottom lands, in the 
canyons, and throughout the mountains, under cottonwood and 
aspen logs, not often among conifers. As the species are mostly tiny, 
some of them smaller than an ordinary pin head, and most of them 
much less than a quarter of an inch in diameter, it requires close 
inspection to discover them. They may be packed with a little moss 
or some green leaves and shipped alive to conchologists for identifi- 
cation.

Ashmunella thomsoniana Ancey. 
This species is recorded from Santa Fe Canyon and the Pecos 
Valley by Pilsbry,! the localities being all east of the Rio Grande. 
Two subspecies are credited to the Pecos drainage in New Mexico. 
Other species are recorded from south of our area. 
Pe obe’e:, ‘little wood shell’ (p‘e, stick, wood; ’obe, shell; ’e-, 
diminutive). 
Ashmunella ashmun Dall. 
The type locality of this species is Bland, not far from El] Rito de 
los Frijoles.2. The species is very abundant at several localities along 
the Rito de los Frijoles. Five immature specimens from near the top 
of the Jemez Mountains at Valle Grande, and four from about half- 
way to the base of the mountains, may be referable to this form, 
though probably belonging to the next. It is likely that the San Ide- 
fonso Indian name given to this form would be applied to the other 
Ashmunella species, as they are so much alike that they would be sep- 
arated only by a skilled conchologist looking for slight differences.

Ashmunella ashmuni robusta Pilsbry. 
This subspecies is somewhat larger than the preceding, and was 
described as from the ‘‘Jemez Mountains near Bland, N. Mex., at 
higher elevations than A. ashmuni.”’ *
