REPORT OF LIEUT. W. L. CARPENTER ON THE COLLECTIONS 

 MADE BY HIM IN 1873, WHILE CONNECTED WITH THE UNITED 

 STATES GEOLOGICAL SURVEY. 



Washington, D. C, January 1, 1874. 



Sir : Having been permitted by tlie courtesy ot my superior officers 

 to accompany the United States geological survey of Colorado, and by 

 yourself kindly appointed naturalist of the party, I take pleasure in pre- 

 senting for your consideration a brief summary of the collections made 

 in this department during the season. 



In ornithology and , oology, a thorough collection, embracing many 

 rare and valuable specimens, was made by Mr. J. H. Batty. The 

 branches to which I paid particular attention, and the collections made 

 by myself, are as follows : 



Hymenoptera. Myriopoda. Parasites. 



Lepidoptera. Eggs of insects. Land- shells. 



Diptera. Larvas. Fish. 



Coleoptera. Chrysalides. Eeptiles. 



Hemiptera. Galls. Mammals. 



Orthoptera. Arachnida. Skeletons. 

 Neuroptera. 



The entomological collection was made as thorough as circumstances 

 would permit ; and a large amount of material obtained for future study, 

 including sediment of streams and i>onds at extreme elevations, which 

 will require a considerable time for examination, and cannot, therefore, 

 appear in this report. The several orders of insects were placed in the 

 hands of eminent scientific gentlemen, specially interested in their 

 study, who cheerfully undertook their examination ; the classification 

 of species as arranged by them is herewith annexed. A separate mis- 

 cellaneous entomological collection was also made in the mountain- 

 region, entirely above timber-line, which I have classified, thinking it 

 would prove interesting in determining the geographical distribution and 

 range of species. As many skeletons of mammals were made as possi- 

 ble, including one of the grizzly bear, which I believe is the first com- 

 plete skeleton of that animal ever secured. 



Regarding the general, results obtained, and the inferences to be 

 drawn therefrom, I can only say that the thorough observations of Dr. 

 A. S. Packard, jr., Dr. Cyrus Thomas, and Dr. Horn, published in the 

 reports of your previous surveys, have been so exhaustive as to leave 

 little of interest to be said which will not be a repetition of former pub- 

 lications. In fact, 1 find that nearly all my notes upon the habits and 

 range of species singularly verify the facts noted by those who have 

 preceded me in this field. I shall, therefore, merely call attention in the 

 catalogue by a brief note to any which may merit particular attention.
