LEPIDOPTERA. 



Cemiostoma laburnella. — I have noticed this pretty little 

 micro in the g"arden here regularly twice a year for over twenty 

 years, but never in anything- like the abundance of the last day 

 or two. The least tap of a laburnum branch or shrub adjoining- 

 dislodged them by the hundred. — A. E. Hall, Sheffield, 17th

GEOLOGY. 



Walrus Remains in Holderness. — Amongst a collection 

 of bones recently received at Hull from the excavations now 

 being made at Kelsey Hill by the North Eastern Railway 

 Company, is a tusk 9 inches in length and 13.4 inches in width. 

 This proves to be the tusk of a Walrus (Trichechus rosmariis). 

 With it were bones of Bos primigeniiis Red Deer. Strangely 

 enough the finest collection of Walrus bones previously obtained 

 in Britain came from excavations made in an adjoining hill by the 

 Hull and Barnslev Railway Company many years ago. These 

 are described in Clement Reid's ' Geology of Holderness,' and 

 some time ago, when endeavouring to trace the Walrus bones, 

 I communicated with Mr. Clement Reid, who wrote as follows : 

 ' From Messrs. Lucas & xAird I borrowed two boxes of bones, 

 obtained whilst ballast was being dug for the new^ docks. These 

 were nearly all unworn, thoug'h broken, vertebrae of Bison, 

 mixed with a few perfect bones of Walrus. All the fragments 

 of bones of Elephant or Rhinoceros were, as far as I could 

 remember, worn. The important point seems to me that, 

 though many of the bones are worn, yet there is a considerable 

 admixture of the spongy vertebras of Bison. The Walrus bones 

 also were quite perfect. The saddest thing remains to be told. 

 When I borrowed the specimens I did not at all like having to 

 return the finest set of Walrus bones yet found in Britain. In 

 1896 or 1897, however, I spoke to Sir A. Geikie about them, 

 fearing that they might be lost to science, as there w^as a 

 Mouse's nest in one of the boxes when it came. He wrote 

 to Sir John Aird, but unfortunately it was too late, the boxes 

 having already been thrown away as useless.' Eventually the 

 Walrus bones referred to were found in a cellar under the Hull 

 Museum, and the remains, together with the tusk recently 

 discovered, now occupy a position in the Geological Gallery 

 there.— T. S.
