parietals rather short. Gastrosteges 234, anal 1-1 ; urosteges 83. Color 

 above light gray crossed by brown transverse diamond-shaped spots, each 

 with a pale transverse centre. Three or four of the most anterior spots 

 are subhexagonal, being truncate at each side. All are surrounded by a 

 pale shade. Each end of every second or third gastrostege is marked with 

 a small dark brown spot, which extends upwards on the first row of scales, 

 and sometimes is confluent with the lateral apex of the dorsal spot. Total 

 length, .304 ; of tail, .054. From Guaymas, Sonora, presented to the 

 National Museum by Mr. H. F. Emerich. No. 13487.

One specimen ; No. 14280. 

 24. Crotalus adamantetjs scutulatus Kenn. 



Five specimens ; Nos. 14225-73-78. The tendency to the development 

 of scuta on the head, especially on the parietal region, is greater than in any 

 specimens I have seen from other localities. 



General Remarks. 



The preceding investigation shows that the reptile fauna of the plain of 

 Chihuahua is that of the adjacent regions of Arizona, New Mexico and 

 Texas, with the accession of a very few forms which are more distinctively 

 Mexican. Only two species come under this designation, viz: Uta bicar- 

 inata and Sceloporus grammicus. The Eutomia cyrtopsis has also an exten- 

 sive Mexican distribution. 



An Obituary Notice of James Macfarlane. By J. P. Lesley. 

 {Read before the American Philosophical Society, December 4, 1SS5.) 



The Society has suffered, by the recent death of its member, Mr. James 

 Macfarlane, of Towanda, in Bradford county, Pa., the loss of a man of 

 distinguished abilities and sterling virtue, universally loved, respected and 

 confided in, a practical business man of the first rank, a lawyer of great 

 reputation, especially for his conduct of railway litigation, a judicious 

 geologist especially devoted to the subject of coal, the author of valuable 

 books in extensive circulation, and a citizen of the Commonwealth 

 entrusted at various times with the conduct of public affairs. 



He was elected to membership in this Society, Jan. 19th, 1883, and 

 regarded it with genuine pleasure and pride, as the best recognition of his

 State, but in this and foreign lands. But his busy life and literary works 

 prevented him from making communications to the Society, at its stated 

 meetings, which he could not attend on account of the distance from his 

 home, the multiplicity of his engagements, and his failing health. 



He became a member of the American Association for the Advancement
