sion. It is right to state that Mr. W. C. Trevelyan, in the 

 2nd edition of his paper upon the botany of the Feroe Isles 

 (printed at Florence), has shortly characterized our present 

 subject under the name of A. argentea (Don). He finds it to 

 be plentiful in those islands. 



1 propose to name and characterize the plant as follows : — 

 Alchemilla conjuncta (Bab. MSS.). Foliis radicalibus peltato-pal- 



matis 5-7 partitis, laciniis oblongis obtusis apice adpresso-serratis 



subtus albo-sericeis ad \ conjunctis. corymbis parvis lateralibus 



terminalibusque distantibus. 

 A. argentea, G. Don, MSS. ! in Borr. Herb., Trevelyan in Bot. of 



Feroe Islands, not Lam. Enc. 1. 77. 



Closely allied to A. alpina, but usually much larger in all 

 its parts, and distinguished by not having its leaflets sepa- 

 rated to their base, broader, more silky beneath, and spread- 

 ing from the petiole in such a manner, that in the radical 

 leaves the two external leaflets almost, if not quite, touch each 

 other, so that at first sight the whole leaf presents the appear- 

 ance of being peltate. The stems have long alternate spread- 

 ing branches which are often again subdivided, and the flow- 

 ers, which are more silky and upon longer stalks than those 

 of A. alpina, are collected into small, nearly simple, distant 

 corymbs. In A. alpina the leaflets are separated to the base, 

 and form a digitate not at all palmate leaf, the outer ones 

 being very distant from each other, or even nearly opposite.

Gerres filamentosus (Cuv. et VaL). 



No. 4. Mr. Gilbert's collection, Sept. 1840. 

 This fish, Mr. Gilbert informs us, is an inhabitant of a fresh- 

 water swamp at Port Essington, but he does not state whether 

 the swamp communicates with the sea or not. The Gerres 

 lineatus is also said to be taken in the freshwater lagoon of 

 Colluco, but as the other species are marine, it is probable that 

 these enter the fresh waters at certain seasons from the sea. 

 Mr. Gilbert's specimen was obtained in the month of Sep- 

 tember. The same species was obtained by Messrs. Quoy 

 and Gaimard at New Guinea, and by Messrs. Kuhl and Van 

 Hasselt at Java. In the * Histoire des Poissons 5 the wooda- 

 wahah of Russell (p. 52. pi. 68.) is considered to belong to this 

 species ; but this appears to be somewhat doubtful, from the
