and that the records were most unreliable, owing to the slight 

 amount of divergence of the various species. 



Mr. Tutt exhibited specimens of Ephippiphora grandcevana 

 from Hartlepool, received from Mr. Gardner. He commented 

 on the long sand tubes formed, the movements of the pupa 

 therein, and the emergence of the imago, bred June 22nd. 



Mr. F. N.Clark read a short paper on " Photomicrography 

 as applied to Entomology," illustrating it by his own photo- 

 graphs.

Mr. Lucas exhibited a very finely marked specimen of 

 Libellula quadrimaculata, var. prccnubila, taken at the Black 

 Pond Esher. 



Mr. R. Adkin exhibited specimens of Pachnobia hyperborea 

 (alpina), bred last year from pupas taken at Rannoch. 



Mr. E. Step exhibited specimens of the hermit crabs 

 Eupagurus pubescens, Kroyer, Eupagurus sculptimanus, Lucas, 

 and A napagurus hyndmanni, Thomps., and read the following 

 note : 



"The small hermit crabs exhibited are among the least 

 known of our indigenous Crustacea, and are not very fre- 

 quently seen in collections. Too frequently, no doubt, they 

 are passed over by collectors as juvenile specimens of the 

 common species {Eu. bernhardus). 



" Eu. pubescens, the downy hermit, appears to have been 

 first recorded as British by Mr. Hyndman, who obtained a 

 specimen lodged in a whelk-shell by dredging at a depth of 

 fifty fathoms at the entrance to Belfast Bay. Thompson 

 sent this specimen to Bell, who figured and described it in 

 the Appendix to his " Stalk-eyed Crustacea," under the name 

 of Pagurus thompsoni ; but it had been previously named by 

 Kroyer Pag. pubescens. The limbs are all furnished with 

 spines and densely clothed with hairs, which are far more 

 evident in the living crab than in a dry specimen. Bell 

 gives a tolerably close description, but one very distinctive 

 feature he omits, i. e. the antennae are furnished with long, 

 pellucid, spreading hairs, and are annulated with dark red- 

 dish-brown and white. The carapace is reddish-brown
