Note on the capture of Lebia Crux-minor. On the 11th of September last, while 

 on a visit to my friend, the Rev. W. M. W. Call, I had the good fortune to capture 

 a specimen of this rare insect, which I brushed into my net from a moist meadow in 

 the parish of Treneglos, one of the wildest and most uncultivated spots in Cornwall. 

 For a week I visited (often twice a day) the same locality, but could not procure a se- 

 cond ; however, the same valley afforded me many rarities, including specimens of 

 Chrysomela geminata, Thyamis holsatica and Nastursii, and a single specimen of the 

 true Gymnaetron Veronicee of Germar, captured at Treglith. — T. Vernon Wollaston ;

Note on the capture of Cordulia alpestris, a species of Dragonfly new to Britain. I 

 had the good fortune to capture a single male specimen of Cordulia alpestris, in the 

 Black forest, Perthshire, in July last. This insect, unique as British, is now in the 

 cabinet of Mr. Dale. — Richard Weaver ; 63, Pershore Street, Birmingham, September

Note on Halisarca Dujardinii. Dujardin has described a sponge in the c Annales 

 des Sciences Naturelles,' No. 8, which he has made the type of a new genus, and de- 

 signated Halisarca, from its fleshy character and the supposed absence of spicula ; and 

 Dr. Johnston, in his excellent history of the British Sponges, has adopted the genus, 

 which is thus described. — " Substance fleshy or rather gelatinous, semitransparent, 

 unorganized, forming an irregular crust on the object to which it adheres.'' In the 

 spring of 1843, I had the good fortune to find this curious species of sponge on the 

 coast near Scarborough, coating the under surface of a small detached mass of sand- 

 stone ; and upon examining a small fragment of it with a microscopic power of 300 

 linear, I found that instead of being destitute of spicula, they were in abundance, but 

 exceedingly minute. They are imbedded in all parts of the fleshy matter, without 

 any definite mode of arrangement. They are exceedingly long in proportion to their 

 diameter, nearly uniform in thickness throughout the whole of their length, and ter- 

 minate hemispherically. The surface of the sponge is thickly studded with oscula, 

 which are nearly of a uniform diameter. From these circumstances it would appear 

 that the new genus, Halisarca, is in fact but one of the various forms of Halichondria.

Note on the Habits of the Hedgehog. The habits of the hedgehog are generally 

 strictly nocturnal ; but on the 27th of last June, about 3 o'clock P.M., whilst walking 

 with my"children in a wood, thinly planted with forest trees, but abounding in low 

 bushes, they called my attention to what they fancied was a large rat coming towards 

 us. I at once saw that it was a hedgehog, proceeding at a moderately fast pace. I 

 secured it, and as it was a female, I regret that I did not examine a bush, thickly 

 matted with grass, towards which it was tending, and into which there was a well pad- 

 ded hole ; as it would probably have appeared that family cares had forced it to roam.
