a shrub, but the other two sometimes appear as great trees. A Cap- 

 paridea too, the beautiful Mcerua angolensis, DeC, appears as a tree, 

 even in the neighbourhood of Loanda, but extremely seldom ; usually- 

 only as a shrub 5-6 feet high. Among my collections several species 

 of Strychnos, and another Loganiacea, likewise occur, most of which 

 may probably prove to be new species. In the woods of Euphorbia 

 {Candelabra, n. sp.) is found a wonderfully beautiful terrestrial 

 Orchidea, with a scape 4-5 feet high, which ends in a spike of a foot 

 long with large yellow flowers. A truly magnificent Crinum (BrouS' 

 sonetii }) luxuriates in boggy places ; and on hilly slopes, the Adan- 

 sonia digitata is nearly covered by a glaucous-leaved Loranthus with 

 deep red flowers. 



It is much to be regretted that excursions in this country are 

 attended with so much expense, and such great inconveniences of all 

 kinds. Although the Portuguese Government allow me £45 per 

 month, I shall nevertheless be under the necessity of contracting 

 heavy debts before I return to Europe, since everything is at least 

 three times dearer here than in London. As there are few roads, 

 and fewer beasts of burden, all baggage, provisions, water, presses, 

 paper, beds, cooking utensils, with the necessary articles for barter 

 (e. g. guns, powder, brandy, cotton goods, glass-pearls, &c.), must be 

 conveyed on the heads of negros ; so that even the shortest excursion 

 of three or four days costs an enormous sum. 



Meanwhile, my reliance is upon England ; that is to say, I anti- 

 cipate that my cases of living plants, insects, seeds, &c., as also a 

 few herbaria of the flora of this neighbourhood, will be duly 

 honoured ; and in that hope, I intend within two or three weeks 

 from this time, to make up a sample-collection for London. About 

 the 1 6th or 1 Sth of the present month, the English Ship of War 

 Penelope will leave here for England, and I shall avail myself of this 

 opportunity to send living plants, as well as seeds and Hymeno- 

 ptera, to Messrs. Wilson Saunders, Hooker, &c.

 belonging to the family Homolidee, found by Mr. Wm. Lobb, at 

 Monterey in California, in the winter of 1850." By Adam White, 

 Esq., F.L.S. &c. 



This species Mr. White stated to be in some respects allied to 

 Lithodes {Echinocerus) cibarius from the Columbia River, but to 

 diff^er from it in the more regularly triangular and depressed form of 

 the carapace, and in the outer antennae having two or three beautiful 

 petaloid processes at the base, instead of the strong thorn-like spines
