noticed on wall near the Lodge. A myitis fluviatilis, a few small specimens 

 at the falls below the Blue Bridge. Mr. R. H. M'Keown, of Leenane, 

 informs me that the Pearl Mussel, Unio margaritlfer, is found in the 

 Bundorragha river, when it is low in dry weather. 



On way home via Westport (a limestone district) I collected the 

 following alive in plantations in the demesne near the river, or in flood 

 material on the banks of latter, dead •.—Hyalinia cellaria, H. alliaria, H. 

 nitidida, H. crystallina, H. fulva ; Helix pygmcea^ H. rotiindata, H. ptilchella, 

 H.rufescens, latter fine large specimens, many collected in little pockets 

 in dry corners under stones, with the spire eaten away, evidently by 

 mice to get at the animal. Cochlicopa hibrica, Pupa anglica, P. cylindracea, 

 Vertigo pygiiicea, Carychium minimum^ Lim7i(za tnuicattila^ fairly large speci- 

 mens in little limestone quarry near falls. Planorbis spirorbis, P. contortus, 

 P. albus, Bythinia tentaculata, Valvata piscijialis, Pisidium ptisilhun. 



The majority of the slugs I sent as collected to Dr. Scharff, who kindly 

 named them for me. Messrs. Adams and Standen looked over the 

 troublesome Zonidda family when we were at Ballycastle, in May, as a 

 number were not fully grown, and required critical determination. In 

 the case of Hyalinia cellaria a number of the specimens looked like the 

 much rarer H. Draparnaudi, but the shells are not adult enough for 

 certainty on this point.

BIRDS. 



The Birds of Rathlln and Ballycastle District. 



The brief and cursory remarks on birds, in my " Observations on the 

 Fauna of Rathlin Island and Ballycastle District," in the July number of 

 The Irish Naturalist, apply more especially to the "district" — i.e., Ballycastle 

 and neighbourhood — and not to Rathlin Island in particular. The 

 sentence, "The Chiffchaff and many other warblers abound" is quite 

 correct when applied, as intended, to the "district"; and, in the 

 sentence immediately preceding, Rathlin is specially named for certain 

 birds we saw there, and these, although not specified, also occur in the 

 "district." I am sorry that Mr. Warren has somewhat misinterpreted 

 my remarks, and must apologise to him, and any others interested, for 

 not writing more explicitly. With the exception of the Cushendun list 

 supplied by Rev. S. A. Brenan, the few birds mentioned in my notes were 

 seen by me and others of the party, and are not quoted from "informa- 

 tion received." It would be very interesting to ascertain whether there 

 has been any substantial increase in the " warbler " population of Rathlin 

 since the " sixties." I am rather inclined to think so, but my time on 

 the island was, unfortunately, too limited to allow of more than a 

 glimpse of its smaller birds.
