13. Mus musculus, L. Common in houses, West Cliff, 

 Swift Creek, Willow Creek, etc. 



14. Thomomys talpoides, subsp. Swift Creek. 



15. Sciurus hudsonius fremonti (Towns.) Allen. A squirrel, 

 presumably this, is very common on the Sangre de Cristo Range 

 They have been observed to place pine cones in running water, 

 as if to make them soft for eating. ^Mrs. M. E. Cusack.) 



16. Tamias quadrivittatus (Say) Rich. A chipmonk, doubt- 

 less this species, is abundant on the Sangre de Cristo Range. 

 They are, however, not equally common each year in some local- 

 ities, which gives the idea that" they may be partially migratory in 

 their habits. 



17. Tamias lateralis (Say) Allen. With the last, but less 

 abundant. 



18. Spermophilus tridecemlineatus (Mitch.) Aud. & Bach. 

 A small, striped gopher, no doubt this species, is found at West 

 Cliff and on Swift Creek. 



19. Cynomys columbianus (Ord.) Allen. Prairie dogs are 

 every where abundant in open ground, and although no speci- 

 mens have been critically examined, it is supposed that they 

 belong to this species. A white variety has been reported from 

 near Silver Cliff (E. Bassick), but we never saw an example. 



20. Castor canadensis, Kuhl. Grape Creek. 



21. Lepus campestris, Bach. Abundant. Short Creek, etc. 



22. Lepus sylvaticus nuttallii (Bach.) Allen. Abundant. 

 West Cliff, etc. 



23. Putorius longicauda, Baird. An ermine observed on 

 Swift Creek, is probably referable to this species.

A NEW LOCALITY FOR HELIX AYRES1ANA. 



This island species heretofore noted from San Miguel, Santa 

 Rosa and Santa Cruz Islands, where it is the only helicoid shell 

 indigenous thereto, I found in October, 1889, very sparingly, 

 after diligent search, upon the middle Anacapa, which is without 

 doubt the southerly and easterly limit of this insular species. 

 The few specimens I obtained are of a decidedly darker color 

 than any I have seen from the other islands, and as they are in 

 danger of almost immediate extermination in their native habitat, 

 from the destruction cf the cacti upon which they live. I have 

 planted colonies upon the main land, in hopes of preserving 

 them and have also sent lLing specimens to some of the islands 

 of the South Pacific for colonization. Lorenzo G. Yates. 



PALMERELLA. 



Prof. E. L. Greene, in Pittonia, I, 297, makes the following 

 statement:
