(Cailliaud) On boring Mollusoa; Prize Essay — pp. 58. Mr. Cailliaud has been 

 witness of the complete act of rotation in Pholas perforating ; which Mr. Robert- 

 son did not see in those observed by him. He considers the operation to be 

 purely mechanical in this family, including Xylophaga and Teredina, and in* 

 Ttredo, Septaria, Fistulana gregata, &c, and explains the application of the mus- 

 cular force exerted. The other boring Mollusca, viz., all which have a proper 

 ligament, bore by means of an acid, and only into calcareous rocks; Saxicava, 

 Petricola, Gastrochcena, Clavagella, Venerupis, Cypricardia, Byssomya, Litho- 

 domus. A similar acid appears to be present in all Mollusca, even the univalves, 

 at least at certain seasons. From the number of boring Mollusca must be ex- 

 cluded several often included in the list, which merely occupy the forsaken bur- 

 rows of the proper boring kinds; such are the species of Fragilis, Fulastra, Ru- 

 picola, Venus, Area, Corbula, Cardita, Galeomma, Unqulina.

(Brants) On the image formed in the compound eye of Articulated animals, 

 with reference to an observation of Goettsche ; with a plate — p. 1-14. (Gun- 

 ning and Harting) Investigations of the origin of the Azote in plants, and the 

 Ammoniacal contents of the Atmosphere — p. 38-60. (Mulder) From what 

 source do plants, not manured, derive their Azote — p. 61-87. Concludes that 

 the Azote of the atmosphere enters into the food of plants only through the 

 medium of the soil. (Harting) Objections to the argument of Mulder, in the 

 preceding paper — p. 88-91. (Staring) The subsidence of the ground in the 

 Netherlands, geologically considered — p. 147-165. (Schlegel) On some new 

 species of venomous Snakes from the Gold Coast — p. 312-317. Seven species 

 of venomous snakes were observed along the coast between Cape Three Points 

 and the Ford of Acra. Naja rhombeata is the most common species. The ne^r 

 species are, 1. Vipera rhinoceros {Cerastes nasicomis, Hallowell Proc. Ac. Phi- 

 ladelphia, iii. 319), distinguished from V. nasicornis by the single supranasal 

 shield of each side, attenuated into a hornlike process, and the slightly cari- 

 nated scales ; the colours also are brighter, and the arrangement of the spots of the 

 head different. 2. V. chloroechis, differing from the rest of the genus in general 

 appearance, form of trunk and tail, and in the colour, and making an approach 

 to {he green Trigonocephali. A very rare native of Upper Guinea, where 

 it ascends the shrubs in pursuit of birds and tree frogs.

The present part contains the report of two Annual Meetings of this Associa- 

 tion, which counts above forty Members; the Tenth held at Haarlem, in August, 

 1854, the Eleventh at Arnbem, in August, 1855. As the state and progress of 

 Entomology in Holland is less known than elsewhere, we notice more particularly 

 the most important scientific communications contained in these Reports. Verloren 

 gave some account of the oviposition and the eggs of Panorpa communis, the deve- 

 lopment of which has been more fully illustrated by Brauer (see the Transactions
