ORTHOPTERA, 

 A Cockroach new to Yorkshire. — Last August. Mr. 

 Malone kindly gave me a large Cockroach from the Bradford- 

 market, which was altogether new to me. I sent it on to ]\Ir. 

 R. Shelford, of the Oxford Museum, who kindly named it 

 Nydihora hrunnea Thunb. It is a South American species. 

 Of course it is ' only an introduction,' but we must bear in 

 mind that all our big cockroaches have been introduced with 

 commerce. Some of them, however, have come to stay ; 

 have found congenial habitations, and have multiplied enor- 

 mously. It is therefore of interest and importance to know 

 the time of their coming. — J. W. Carter, Bradford. 



Leucophcea surinamensis Linn, at Bradford. — In 1906 

 I had a specimen of this Cockroach brought in from the Brad- 

 ford market. During 1907-8 Mr. F. Rhodes gave me several 

 from a hot-house in Lister Park, Manningham, where it has 

 become firmly established. — J. \V. Carter, Bradford.

Vertigo alpestris at Ingleton. — The members of the 

 Leeds Branch of the Conchological Society held a joint ramble 

 with the members of the Manchester Branch, at Ingleton, on 

 the 12th September, 1908. Thirty-six species of landshells, 

 and nine slugs were recorded during the day. Mr. J. \V. Taylor 

 was fortunate in adding a second authentic locality for l^ertigo 

 alpestris. This species, and Vertigo mimitissima are the most 

 uncommon of the genus that are known to occur in York- 

 shire. It is interesting to add another locality to the very 

 few already known for these rare species. It is perhaps as 

 well to state that it occurred under stones on the top of a wall 

 in Beesley Glen. This appears to be the general habitat for 

 this species, as it is found under similar conditions in other 

 localities. It was first recorded from a garden wall at Bingley, 

 by Mr. J. A. Hargreaves in 1887. — F. Booth.

The Hybrid Oak in Yorkshire and other parts of 



Britain. — There appears to be no definite record of the occur- 

 rence of the Hybrid Oak {Qiiercus Rohitr x sessiliflora) in Britain. 

 During the summer of 1908, I found it in the following 



1909 March i.
