Pupa ringens, Jeff., and var. pallida. This interesting species 

 occurs at the Cloch, Shielhill Glen, and Rottenburn Glen 

 (west end of Loch Thorn), where I also find the variety. 



Vertigo pygmaea, Drap. Very common in Rottenburn Glen. 

 „ ,, var. pallida. Rottenburn Glen, occasional. 



V. substriata, Jeff. Rottenburn Glen, rare. 



V. edentula, Drap. Shielhill Glen, Cloch. 



Balia perversa, L. Skelmorlie. 



Acme lineata, Drap. One specimen of this shell was obtained 

 at the Cloch in May, 1882, by my son, Mr. Andrew Scott. 



Mr. J. M. Campbell exhibited a young living Alligator, Alligator 

 mississippiensis, from the Mississippi ; and in the course of some 

 remarks he described the characters which distinguish the Alligators 

 from the Crocodiles and Gavials. 



Mr. James Lumsden, E.Z.S., in exhibiting a Pectoral Sandpiper, 

 Tringa macidata, shot at Loch Lomond by Sir George H. Leith 

 Buchanan, Bart., Corresponding Member, said that during the year 

 1881 several new species had been added to the list of Loch Lomond 

 birds, but for 1882 there was only one to add, and that the Pectoral 

 Sandpiper. On 24th November, 1882, Sir George H. Leith 

 Buchanan obtained a specimen of this rare species when out snipe- 

 shooting on the banks of Loch Lomond, near the mouth of the 

 Endrick ; and he (Mr. Lumsden) trusted the following extract from 

 Sir George's letter would satisfy those naturalists who object to any 

 rare birds being shot, that the present specimen was obtained by 

 accident. " On the 24th November I shot a specimen of the 

 Pectoral Sandpiper of America. It rose from some rushes, and I 

 took it for a Jack-snipe until I picked it up. As it was blowing 

 very hard at the time with snow and rain, I could not see distinctly." 

 The specimen was a female, and its stomach contained small insects. 



This species has only once been recorded from any part of Scot- 

 land, a specimen having been shot at .the mouth of the Don, in 

 Aberdeenshire, in October, 1867, as mentioned by Mr. Gray in the 

 Birds of the West of Scotland, who includes it on the authority of 

 Mr. Angus. In England it is more common, about twenty instances 

 of its occurrence being on record. The home of the Pectoral Sand- 

 piper is America, and it is met with in Europe only as a rare 

 straggler. It is widely distributed over North America, is recorded 

 from South America as far south as Brazil and Peru, and is very
