ANALYSIS OF PERIODICAL M'ORKS ON ZOOLOGY AND BOTANY. 



Soxverbys Mineral Conchology. No. 67. 

 PI. 384. Sigaretus canalkiilahis, from Hordwell, described 

 as new, and the only fossil species known of the genus. Spec. 

 Char. Obovate, convex, longitudinally striated ; spire pointed,' 

 Its turns (or rather volutions^ distinguished by a canal ; um- 

 bilicus large. PI. 385. Nerifina concava and unipUcata : we 

 by no means think the latter is a fresh-water shell ; it is at 

 variance with the generic character that precedes its descrip- 

 tion, and was confessedly found in a bed of sand (near Wool- 

 wich) which contained a mixture of fluviahc and marine shells. 

 PI. 386. Pleiirotoma prisms (Murex. Brander 25 and 44). 

 PI. 387. P.fusiformis, P. brevirostrum, doubtful if belonging 

 to this genus. P. U-vigata, ditto. PI. 388. Osirea bcllova- 

 cma, and cdiih7ia, of Lamarck; both from the sand-pits near 

 Woolwich. 



Soxvcrbys Genera of Shells. No. 11. 

 Galeolaria. Mr. Sowerby says very truly, that this is a 

 genus not hkely to be admitted by the generality of concholo- 

 gists ; It has been pubhshed under Lamarck's 7iame, but since 

 that naturalist has been affected with blmdness. Scalaria, 

 the type of which is the femous Wentletrap shell, or Turbo 

 scalaris of Linn. ; four recent, and one fossil species are deli- 

 neated. BiROSTRiTES, an extraordinary fossil genus, accom- 

 panied by a figure of B. incequilobm. Vitrina, with good 

 figures and judicious remarks on two species. Conia of 

 Leach ; separated from i?fl/cm/s, on account of having only 

 four valves, a character affording, in our opinion, good di- 

 stinctions for a section, but not sufficient for the creation of a 

 genus. Gastroch(ena, Spengler; with an illustrative plate 

 ot G. modiolina and cunciformis. 



Curiis's Botanical Magazifie. No. 432. 

 PI. 2370. Sedum spurinm ? of WiUd. Enum. Cistus (or 

 v^^\vix Helianthemum) Barrelicri, of Tenore, an acute botanist 

 ot Naples Loasa nitida, Willd. from Peru. Ncmophila Pha- 

 cehoides, Barton FI. Am. Achania mollis, Willd. ; to the de- 

 scription of thisjilant, we slialladd that its flowers are partially 

 opened during the hottest part oi'the day; and that in a na- 

 tive state It grows to the height of a moderate sized apple 

 tree ; but witli long, tiiin, and straggling branches. Hyperi- 

 cum nralum, a new plant from Nepal, first discovered by 

 J)r. Buchanan. " //. fruticosi.m, S-gynum ; foliis ellipticis 

 mucromilatis giabns nitidis, floribus tenninalibus siibcorym- 



bosis,
