there are perennial streams. Prof. T. D. A. Cockerell has a manu- 

 script list of New Mexico shells prepared by Rev. E. H. Ashmim, 

 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 PJiysa, though Lymnxa palustris IMiiller 

 from Taos, and L. desidiosa Say (probably L. ohrussa Say) and 

 Planorbis parvus Say, both from Santa Fe, are included in Aslinaun'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. 



P'e'o^e'e", 'little wood shell' (p'e, stick, wood; 'dbe, shell; 'e', 

 diminutive). 



Ashmunella ashmuni Dall. 

 The type locality of this species is Bland, not far from El Rito de 

 los Frijoles.^ 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- 

 wa.y to the base of the mountains, may be referable to tliis form, 

 though probably belonging to the next. It is likely that the San Ilde- 

 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." ^
