The insects -were not methodically collected, and but few, chiefly 

 myriapods, which are very abundant in the mountains, were brought 

 home. A small collectiou of spiders made consists of ten species of 

 Araneje {Drassidce 2, Lycosa 5, Attus 1, Thomisus 2) ; and four species 

 of PhalanGtE^ {Phalangein 3, Gonyleptes 1). All of these species are 

 believed by Mr. E. H. Emerton, who has examined them, to be unde- 

 scribed, though in part identical with forms previously collected in 

 Colorado. A description is not attempted herewith, because the mate- 

 rial is not at hand for proper study and comparison. Further collections 

 and observation in this branch of entomology are particularly desirable 

 from the mountainous regions of all the Territories. 



Land and fresh-water shells comprise the largest part of the material 

 brought home. They were made a specialty ; and the fact that next to 

 nothing of this class had ever been reported from Colorado, and but 

 little was known at all of the mollusca of the Rocky Mountain region, 

 was deemed a sufficient excuse for what might seem too exclusive 

 attention to this department of natural history, which does not present 

 to the careless mind such striking attractions as the study of the higher 

 vertebrates. 



No fishes were collected, although numerous attempts were made. 

 The majority of our time was spent where they seemed to be entirely 

 absent, or so extremely scarce that, although all were interested in the 

 capture of certain species, not a trout graced our table during the whole 

 trip. 



Some snakes and frogs were secured at Hot Springs, Middle Park, 

 and a number of Aniblystoma seen for the first and last time. Eeptiles 

 were taken wherever they occurred after this, also, except upon the 

 long side-trip mentioned above, where it was impracticable to ijreserve 

 anything greater than could be put in a pocket-bottle of alcohol. 

 The marsh between the Animas and La Plata was a fine locality for 

 batrachians. South of the mountains, lizards began to appear in great 

 numbers and variety, and increased as we got farther out upon the dry 

 plains. Camp 20 furnished us our only rattlesnake, and I do not re- 

 member any other camp at which we were even suspicious of their 

 presence. 



In conclusion, I wish to express to Mr. Wm. H. Jackson, director of 

 our party, the appreciation I have of his hearty co-operation and genial 

 sympathy, through which he not only afforded me opportunities I would 

 not otherwise have had, but added immensely to my personal enjoyment 

 of this delightful trip.
