144 president's address. 



He has also added many localities for species before recorded. 

 Several Dipterous Insects, apparently new, were noticed, but not 

 having a catalogue of that order, it is not necessary to enumerate 

 them here. Mr. Bold has captured Ragonicha pilosus, near 

 Heaton; and also mentions the capture oi Astynomus ^dilis, on 

 board of a grain laden ship from Stettin. The latter, which is a 

 northern species, is only of interest, in so much, as it indicates 

 how liable our fauna is to be increased by our commercial inter- 

 course, and shows the great care with which catalogues of our 

 indigenous species should be compiled." 



Notices of rare Mollusks found or taken on the Coast of Nortliiim- 

 herland, in 1851. By Mr. R. Howse, Jun. — "I obtained from the 

 fishing boats which visit the inner edge of the Dogger Bank, in 

 the early part of the year, two living specimens of Buccinum 

 Dalei. This rare mollusk first appeared in our sea during the 

 formation of the tertiary deposits of Norfolk and Suffolk. It is 

 very interesting, therefore, to find it still inhabiting the deep 

 water of our coast. Dead specimens, also, of Trochus alahastrum, 

 Tellina proxima, and Astarte aixtica were brought in from the 

 same fishing ground. These have not yet been taken in a living 

 state, on the east coast. 



Mr. M'Andrew, of Liverpool, paid a visit in his yacht, this 

 summer, for the purpose of exploring the marine fauna of our 

 coast; but, owing to the want of precise information relative to 

 the position of the fishing bank, did not meet with a very abun- 

 dant harvest. The following, however, occurred new to the 

 district: — Ovula acuta, Syndosmya intermedia, and Cardium 

 JSuecicum. Some species, before considered rare, were also met 

 with in considerable abundance." 



Notice of the occurrence of Cenia CocJcsii, on the Durham 

 Coast. By Mr. Albany Hancock. — "I took a single individual 

 of Cenia Cocksii, last July (1851), on Marsden Rock. This 

 curious, minute, and rare mollusk has hitherto been met with only 

 at Falmouth, where it was discovered, in 1847, by the gentleman 

 after whom it is named. By its occurrence in the North of 

 England, it would appear, however, to be widely distributed on 

 our shores."
