arrangement is in genera which are widely sepa- 

 rated, and how similar it is in the several species 

 of each genus, and in genera which are closely 

 allied. 



The tissue is generally gathered into two prin- 

 cipal, and one or more secondary bundles ; though 

 sometimes the principal bundles are fused into one. 

 Thus Polypodiim vulgare has two principal and one 

 small secondary bundle (a). These as they ap- 

 proach the leafy portion of the frond are fused into 

 one bundle of^three projections. In P. dryopteris

the smaller bundle disappears (I). Lastreaftlix-mas 

 (c) contains two principal, tbree secondary, and a 

 small bundle on one side only ; all these bundles 

 being circular. L. dilatata (d) has the same ar- 



rangement, without the small bundle, and the 

 middle secondary bundle is oval. There are in L. 

 fcenisecii (e) only two secondary bundles. In 

 Polystichum lobatum (f) the principal bundles are 

 oval, as well as the middle secondary. P. angulare 

 (g) differs very little from this, except that the 

 principals are ovate and the middle one round. 

 Cystopteris dentata {li) has two reniform bundles. 

 Those of Athyrium filix-famina (i) are somewhat 

 similar, the primary and secondary bundles on each 

 side seeming to be fused together. In Asplenium 

 trichomanes (k) there is but one bundle, which 

 is circular. In Scolopendrium vulgare (I) the 

 bundles are semicircular, and joined back to back 

 near their upper cusps. The bundles of Pteris 

 aqidlina are curiously disposed so as to form with 

 the brown tissue the figure of a tree (m). The 

 lower figure is a section across one of the branches 

 of the frond, and shows the tissue more regularly 

 disposed. The bundles of Adiantum capillus Veneris 

 are fused so as to be saddle-shaped («) ; and of 

 Osmunda regalis so as to be semicircular, with the 

 cusps turned in (o.) 



I have not had an opportunity of examining any 

 other native ferns. Others of your readers may 

 be able perhaps to complete the series.

HARE VISITORS AT BRIGHTON. 



WHILE Woolwich has been painfully visited 

 by the so-called mosquito, we, in the, by 

 courtesy, " Prince of Watering-places," have, during 

 this extraordinary summer, been favoured by the 

 presence of sundry rare Lepidoptera; while some 

 kinds which in ordinary years have been but sparsely 

 seen, have this summer been abundant, and others, 

 apparently astonished at the unusual state of things, 

 have produced double broods. 



First among rarities stands that great prize to 

 the entomologist, the Clifton Nonpareil {Catocala 

 Fraxini), which well deserves the name Catocala — 

 " beautiful beneath ;" for its lilac-coloured anterior 

 wings are certainly very beautiful. This specimen 

 was caught by a page-boy in one of the hotels, and 

 taken alive in a box to Swaysland, of Queen's Road, 

 by whom it has been sold, to enrich the collection 

 of Mr. Bond. 



Next came a couple of Striped Hawk-moths 

 (Deilephila Livornica), one of which was taken on 

 the door of an outbuilding belonging to an eating- 

 house in Church Street, and the other at a baker's 

 shop in Edward Street. Both these, when taken 

 to Swaysland, were in a very much worn and 

 battered condition. In addition to these might 

 be mentioned two peculiar catches, viz., a very fine 

 Death's-head Hawk-moth (Acherontia Atropos) in 

 good condition, and a battered specimen of Sphinx
