1896.1 SCHARFF. — A Supposed Lajid-Lockcd Salmo?t. 17 



To return to Mr. Ussher's specimen, it would appear from 

 information kindly given me by the discoverer, that during 

 the usual condition of the small stream a Salmon ascending 

 from the sea would be stopped not only by the grating 

 referred to, but also by another equally formidable obstacle. 

 The stream after leaving Mr. Ussher's premises sinks into 

 a limestone cavern and runs underground for more than 

 a mile, so that as he remarks " by no possibility could a fish 

 come up this stream from the sea." During floods, however, 

 it occasionally happens, that a separate communication is 

 formed between the upper part of the small stream and the 

 river Finisk into which it flows, so that fish could then come 

 up, and Salmon peaP have actually been known to reach the 

 glen above Mr. Ussher's house in this way. Several such fish 

 were seen in a deep part of the stream about two years ago, 

 and Mr. Ussher thinks the present specimen may be one of 

 these, having being confined in the stream during that time. 



Although this cannot be considered an undoubted instance 

 of a Salmon reaching maturity in fresh water, I think the case 

 deserves special mention, and its record may lead to continued 

 observations on the habits of the salmon tribe in Ireland. 



^Though a young Sea Trout is generally known as a " peal," the term 

 is often indiscriminately applied to it as well as to young Salmon.

 November 21st.— The Club met at Mr. G. H. Carpenter's, who showed 

 specimens of Ixodes marginatus, Leach, which he had received from Dr. 

 Scott, who reported that these ticks were so extremely abundant in the 

 west of Ireland during the past summer as to be a serious annoyance, 

 persons venturing to lie on heath in certain places becoming covered with
