188 Mr, W. H. Coleman on a new species of (Enanthe. 



fers from the former. Its palpi are long and red-brown, witli a 

 black annulus at the base of the cubital and radial joints ; the 

 cubital joint gradually increases in bulk to its extremity and is 

 curved downwards, and the radial, which greatly exceeds it in 

 length, projects a minute bifid apophysis from its extremity, on 

 the outer side ; the palpal organs have a prominent bifid process 

 at their upper part, on the inner side, and a long, slendei', curved, 

 black spine at their extremity, which is directed upwards. 



A collection of living spiders sent to me in September 1843 

 from Ellesmere, in Shropshire, by Miss Margaret B. Lewis, of 

 Cichle, Anglesey, contained a young male Epe'ira simiJis, which, 

 as the digital joints of its palpi were very tumid, had to undergo 

 its final change of integument before it arrived at matm'ity. On 

 comparing this individual with males of Epe'ira calophylla in the 

 same state, I perceived that its palpi were much shorter, and that 

 the protuberance at the upper part of the under side of the digi- 

 tal joint was decidedly smaller than in the latter species. The 

 sides of the cephalo-thorax in the specimen received from Miss 

 Lewis were finely bordered with black.

[Witli a Plate.] 

 Under the name of (Enanthe Phellandrium, two distinct forms 

 have long been confounded. The first, which is the Phellan- 

 drium aquaticum of Linnseus, and the QLnanthe Phellandrium of 

 Smith and others, is figured in 'E. B.^(t.684); the other, though 

 frequent in the rivers of the south-east of England, has hitherto 

 been much overlooked ; not being noticed even as a variety in 

 any work to which I have access, except by Dillenius in his edi- 

 tion of ' Ray's Synopsis,' until I di'ew the attention of Mr. C. C. 

 Babington to it. It is noticed in that gentleman's ' Manual of 

 British Botany' (p. 131), under the name of (E. Phellandrium 

 ^ fluviatilis ; and I now venture to propose it as a distinct spe- 

 cies, with the title of (E. fluviatilis, offering the following cha- 

 racters for it and its ally : — 



1. (Enanthe Phellandrium (" Lamk.") ; caule erecto deorsum incras- 

 sato, fibris ad genicula verticillatis ; foUis tripinnatis, segmentis 

 simplicibus pinnatifidisve, snbmersorum capillaceis, superiorum 

 divaricatis ; umbellis oppositifoliis ; fructu ovato stylis suberectis 

 duplo longiore. Biennis. Habitat in aquis stagnantibus. 



2. (Enanthe fluviatilis ; caule fluitante sursum incrassato basi repente 

 ad genicula radicante ; foliis bijjinnatis, segmentis simplicibus 

 pinnatifidisve, submersorum pellucidis cuneatis fissis, nervis plu-
