266 Field Columbian Museum — Reports, Vol. II. 



In the Department of Zoology 1,778 specimens of Mammals have 

 been added to the collection during the past year — 121 by purchase, 

 57 by donations, and 1,600 collected in the field. The most important 

 specimens presented were six Caribou from Newfoundland, the gift of 

 Mr. V. Shaw Kennedy, and which eventually will be mounted in one 

 group . Among the notable purchases were a male ' ' O vis ammon , ' ' with 

 very fine horns measuring ig^ inches at base, 53^^ inches in length, 

 and 36 inches from tip to tip, thus nearly equalling the largest head 

 recorded; a very fine silver fox, V. p. argentata, 5 musk oxen from 

 the Mackenzie River district, the true "Ovibos moschatus," and a 

 male, female, and young adult female of the Saiga Antelope, in the 

 rare snow-white winter pelage. Additions to the collection of fishes 

 have been comparatively few during the past year, comprising but 80 

 specimens in all, of which 54 were donated and 26 collected in the field. 

 No purchases were made. A specimen of Alligator Garpike, donated 

 by Mr. McCrea, is 8 feet in length, and represents the largest species 

 of our fresh-water fishes. Of Lizards, 157 specimens were collected in 

 California and Mexico and added to the collection, and 54 Snakes, all 

 collected in California and Mexico, save one presented by Dr. Roerhig, 

 from Kentucky. Seven thousand two hundred and twenty-seven 

 entomological specimens have been added to the collection during the 

 past year, 6,776 by purchase, 119 donated, and 332 collected in the 

 field by the Assistant Curator. The most important acquisition was 

 the purchase of the collection of Prof. Arthur J. Snyder, containing 

 5,564 Butterflies and Moths from America north of Mexico, and 409 

 Butterflies and Moths foreign to these limits. The genus Argynnis is 

 strongly represented, having over 750 specimens, and the genus Cato- 

 cala also exhibits over 450 specimens, thus affording a fairly full rep- 

 resentation of these perplexing genera. Local species from different 

 places in Illinois are well represented, and about 95 per cent of the 

 entire collection possesses exact and proper data. Eleven hundred 

 and forty-seven shell specimens were added to the collection, 625 pur- 

 chased, and 522 collected in the field. The classification of accessions
