mally developed as a bifid anipliigastrioid scale so closely re- 

 sembling tbe scale" a; ", in form and position, as to raise the 

 presumption of tbe two being " serially liomologons." The first 

 lateral leaf (/) of the branch may be noted, with its upper lobe 

 relatively very small as compared with the full-sized helmet- 

 shaped auricle. In this figure I have not indicated the minute 

 clavate hair {stylus auriculi) which is jjlaced at the side of the 

 auricle furthest from the ujiper lobe. Kote also the auricles 

 (au) of two lateral leaves towards upper part of branch, developed 

 as flat and pointed lobes. 



Fig. 2. Portion of shoot, at place of origin of a branch. Seen on dorsal 

 aspect. The base of leaf " y" is seen to be continuous with that 

 of scale "a; " by a raised line or ridge. At the point where the 

 base of scale x curves up to meet that of leaf "2/", there is a 

 minute clavate hair {li) quite similar to a " stylus auriculi." If, 

 however, I am right in viewing scale ".t" as the auricle, this 

 hair cannot represent the stylus which, as already stated, is on 

 the far side of the auricle from the upper leaf-lobe. 

 Madothcca [Porella) jjlatyphylla. 



Figs. 3 and 4. Ventral view of portion of stem from which a lateral branch 

 springs. In both figures, and especially in fig. 4, the base 

 of scale ".t" extends downwards on the main axis far below 

 the origin of the branch. 



Fig. 5. Dorsal view of portion of shoot from which a lateral branch springs. 

 In the specimen figured, the base of leaf " y " runs down very 

 nearly (somewhat unusually near) to that of scale "a; " ; but, as 

 regards this plant, Leitgeb's statement as to the absence of any 

 connection between the two parts seems to be correct. 



Account of a Botanical Journey to the West African Coast, 

 loith List of Plants found. By J. Eattray, M.A,, 

 B.Sc, F.E.S.E. 



(ReadSth July 1886.) 

 The following list contains a record of the plants which 

 I collected in the vicinity of the coast at various places on 

 the islands and mainland of West Tropical Africa, from 

 December 1885 to March 1886, during the cruise of the 

 S.S. " Buccaneer." This steamer, which is the property of 

 the Silvertown Gutta Percha and India-Rubber Company of 

 Silvertown, Essex, was at this time engaged in sounding 

 along the line of the new submarine telegraph cable, 

 which is at present being constructed along the west 

 coast of Africa ; and by the liberality of the Messrs Gray 

 of the above company, as well as by the kindness of Dr 

 John Murray, director of H.M. "Challenger" Commission, I 

 was privileged to accompany the expedition, and, under 

 the supervision of J. Y. Buchanan, Esq., of the " Challenger" 

 Expedition, to make collections both of natural history and 

 botanical specimens.
