134 The Irish Naturalist. June, 



arranging, classifying, and naming the Grainger collection, with the 

 view of developing its educational character. 



J. ]\I. Dickson seconded the motion. The collection was almost 

 valueless from an instructive standpoint, as Irish antiquities were mixed 

 with vSouth vSea Island exhibits, while geological specimens were side by 

 side with old flint heads. The collection would be valuable if properly 

 classified. 



The resolution was passed unanimously. 



Robert Wei^CH then showed a number of very interesting limelight 

 views of scenery at Sligo and its neighbourhood, where the Club will 

 enjoy their long excursion in July. 



DUBLIN MICROSCOPICAL CLUB. 



March 9. — The Club met at Leinster House. 



J. N. Hai^berT showed some caddis cases of peculiar construction, 

 with larvae, found in the River Tolka. The cases are small, measuring 

 only 4 millimetres in length. They are oval iu shape and laterally com- 

 pressed, formed of two valves of finely spun material, joined together 

 along the edges, but open in front. The larvae were fairly active when 

 undisturbed. The cases closely resemble those made by species of 

 Hydroptila. 



WILI^OUGHBY Dade showed living specimens of freshwater Polyzoa. 



APRiiy 13 — The Club met at Leinster House. 



J. N. HaIvBERT showed Midcopsis orbicularis, MuUer, a rather local 

 species of water-mit^ from Lough Derevaragh. 



G. H. Carpenter showed s-pi^chw^nsoi Nvanura ciironetla, a neWvSpecies 

 of Springtail from the Sandwich Islands, recently described and figured 

 by exhibitor in vol. iii. of the " Fauna Hawaiiensis." The maxilke, dis- 

 sected out of the head, were demonstrated under a high power. 



May 10.— The Club met at Leinster House. Dr. J A. ScoTT, Presi- 

 dent, in the chair. Officers for the session 1504-5 were elected as 

 follows:-- President, R. F. Scharff, Ph.D.; Vice president, Geo. PI.

 the chair, 



Dr. M'Ardi^E exhibited Sphcerocm pus terrestris, Mich., which was col- 

 lected by Mr. W. H. Burnell in Norfolk where it occurs in considerable 

 quantity near the sea shore, and also 6 to J2 miles inland, in clover and 

 turnip fields. It is one of the most remarkable of the frondose liver- 

 worts; the lobes of the frond are concealed by the aggregate inflated 

 perianths, which are sessile and pyriform, and the plants grow in crowded 

 patches. The capsule is very delicate iu structure, crowned with a
