3. The species of Ventilago, a genus of Bhamnaceae. Mr. Benthain reduces the Indian species, of which sufficient material has been received, to three, of which diagnoses are given.
4. The Memecyla of Cuming's collections, with the synonymy of four species.
5. A Chinese species of Calogyne, a genus of Groodeniaceae. Curious as the second species of the order, apart from the mari- time Sccevolas, found out of Australia. It was collected near Amoy.

Borszczow, El. — Die Aralo-Caspischen Calligoneen. Petersb. Mem. Tom. in. No. 1. 45 pp. with 3 plates.
Contains observations on the history and literature of the genus Calliffomcm, Linn, (with which the genera Fterococcus, Pall, and Calliphysa, P. et M. are united), its modus crescendi, physiognomy, development, geographical distribution and sta- tistics, properties and uses.
The total number of species is reckoned at 25, all of which are exclusively Asiatic, with the exception of G. comosum, which extends from Persia, across North Africa to the Canaries. The majority of species — at least 14— are peculiar to the Aralo- Caspian basin. Many of the species of Calligonum afford a gummy product, as observed by Pallas, which flows from wounds both in the branches and older stems ; in very hot weather exuding from herbaceous parts of the plant. The commonest species, C. Pallasia, besides serving as a good fuel, furnishes the food of the Steppe-mice (Cricetus, Meriones) which live under its bushes. Most of the species are capable of affording a dye, which has not, however, been investigated. Twenty Calligonums are described ; eleven of them, discovered by Herr Borszczow on his journey in 1857-8, as new.
