HARD WICKE'S SCIENCE- G OSSIP. 



Lonsdale had applied the term to "a very similar 

 corallum, which he, however, places with the genus 

 Fenestella, and figures with only the two rows of 

 pores usual in that genus." 



F. pat ida, M'Coy, and F. rigidula, M'Coy, are 

 good forms and very well described. The corallum 

 of F. patula is small and semicircular, about half an 

 inch in diameter. The interstices are broad, strongly 

 carinate, slightly flexuous ; the dissepiments are 

 strong, and the fenestrules are a little wider than the 

 interstices ; the pores are large and prominent, about 

 3 or 4 to length of fenestrule. Its general features 

 and character are very much like some of the smaller 

 species of the Carboniferous limestone. The figure 

 of F. rigidula is peculiar and striking, and it much 

 resembles some of the Devonian species of Nicholson. 

 The following, however, is M 'Coy's note on the 

 synonyms of the several species :— 



"Fenestella antiqua, Lonsdale = F. subantiqua, 



D'Orb. 



F. antiqua, Goldfuss, is a distinct Devonian form. 



F.prisca, Goldfuss, Silurian = F. rigidula, M'Coy. 



F. elegans, Hall, Silurian = F. rigidula, M'Coy. 



F. assimilis, Lonsdale, Silurian." 



My list contains the names of three other forms. 

 Dawson describes one by the name F. Lyelli, and 

 Hall figures and describes two other species from the 

 Clinton series of America,—^, aibosa and F. tenui- 

 ceps. There are figures of these species, I believe, in 

 Dana's Manual. 



I could not pretend to give anything'like exactness 

 to my review of the Silurian species of Fenestella. 

 To say that the whole of the descriptions are very 

 foggy, would be perhaps vulgar denunciation, but it 

 would be nevertheless a fact. And before altering 

 my formerly written paragraph, which was less 

 sweeping than this, I have gone over again the whole 

 of M 'Coy's figures and descriptions. These are 

 good so far as they go, but they do not come up to a 

 proper analysis of the specific characters of the genus 

 which modern biological, or even palreontological 

 studies demand. Too much dependence has been 

 placed upon the isolated fragments, which give only 

 a partial view of the true ideal of specific type. In 

 reviewing the Carboniferous Fenestella I shall be able 

 to make this more clear.

[I should be glad to correspond with any student 

 who has described or undescribed species of Fenes- 

 tella in his cabinet, for the purpose of more accurate 

 identification.] 



Cotoneaster VULGARIS. — Could I ascertain 

 whether this plant still exists on Great Orme's Head ? 

 The habitat I have down for it is, on rocks above 

 the copper-mines. Along with two friends I worked 

 the locality well, without avail, last month : probably 

 it has "ot exterminated. — II. T. G. 



HOLIDAY RAMBLES IN ST. OUEN'S BAY' 



" Q HALL it be Scotland or Jersey? " was the ques- 

 O tion put when arranging for a botanical tour; 

 and though the flora of Clova, Glen Isla, Braemar, 

 and the Grampians is sufficient in itself to make a 

 holiday enjoyable, but when the additional advantages 

 of lovely scenery and health-giving mountain breezes 

 are added, it must indeed be a rich and peculiar flora 

 to outweigh them ; but possibly it was the long 

 monotonous spring, with its absence of sun, that 

 caused the Channel Islands to exert a spell so mag- 

 netic that not even the presence of the "silvery 

 streak " was sufficient to break or neutralize its in- 

 fluence. So, having prepared for work by spending 

 a day among the oaks of Whittlebury Forest, whose 

 natural history has yet to be written, and glorying in 

 another at Kew, we proceeded with considerable 

 misgivings to cross from Southampton by a passage 

 whose horrors had been sufficiently dwelt upon by 

 candid friends ; but, thanks to the soporific effect of 

 the daily literature we had assimilated, we slept a 

 dreamless sleep as we passed through the Solent and 

 the chops of the Channel. Arriving at St. Helier's, 

 in Jersey, we noticed the slopes of Fort Regent were 

 brilliant with Medicago maculata, Silene Angli:a, 

 Linum angustifolium, Tragopogon porrifolius, Sedum 

 Anglicum, and two or three specimens of Gladiolus, 

 which had established themselves there. But it would 

 be wearisome to give in detail the various plants seen 

 on the different days spent in Jersey ; sufficient to 

 say, that, having beautiful weather we visited the 

 rocky Corbieres, home of the seabirds, enjoyed the 

 delightful breezes on the samphire-covered cliffs of 

 Pleinmont, the only Jersey locality for A. ca pill us 

 veneris, admired the ivy-covered castle of Mont 

 Orgueil, the shady lanes of St. Saviour's, home of 

 Arum Italicum and Sibthorpia, and had taken the 

 rather noisy coach-rides by Beauly Bay, with its view 

 of sunny France, and the romantic gardens of Rozel, 

 not to speak of the sea-bathing, which the firm sands 

 and clear water render so pleasant, and the entomolo- 

 gical hunts after Thecla rubi, Cinxia, Edusa, Cardui, 

 and Daplidice, on the hot slopes of Noirmont Point 

 and Greve de Lecq ; while the enormous cow-cab- 

 bages, the fig-trees, and extensive vineries had been 

 properly inspected. So, in order to give some idea 

 of the peculiarly rich and extensive flora of Jersey, 

 one day shall be used as a sample, comprising, as it 

 did, some of the best and most typical plants. Its 

 route may be shortly given as follows : from St. He- 

 lier's to Beaumont, thence to St. Ouen's on to L'Etac, 

 returning by St. Ouen's Bay to La Moye and St. Bre- 

 lade's. The distance walked would be from 24 to 26 

 miles. The success of the day was owing to the 

 company of Mr. Piquet, who is compiling a new flora 

 of Jersey, and the previous reading up of Babington's 

 "Flora Samicrc." Shortly after leaving the nau- 

 tical-looking station of St. Helier's, the rail, which
