JJe.ruosa y pallida, " floribus pallidis, spica sub-simplici :" probably, Mr. L. 

 thinks, a distinct s >ecies. — Erythrina speciosa. — Dimella strumosa, " foliis 

 kete viridibus, omnino Ia;vibus (latitudine, ubi latioribus, subunciali) : pa- 

 nicula laxa, numerosa, decoinposita : corolla? pen lulo-cernua? laciniis re- 

 flexis, alterne samratius 3-5-lineatis : filainentis cum struma obesa satura- 

 tes colorata antherifera apice articulatis : pediccllis flore paulo breviori- 

 bus," lately observed in New South Wales by Mr. Cunningham, and does 

 not seem reducible to any of the seven species of Mr. Brown. — Schizopeta- 

 Ion Walkerl, introduced from Chili by Mr. Francis Place ; an elaborate cha- 

 racter by Mr. Brown accompanies the description. — Ocymum febrifugum suf- 

 fruticosum pubescens, " foliis ovato-lanceolatis crenatis peticlatis, verticillis 

 terminations racemosis, bracteis rhombeis deciduis, corolla calyci subaequali." 

 From Sierra Leone. Very similar to O.heptodon of M. de Beauvais.— Cur- 

 culigo latifolia. 



PI. 755. Stapelia normalis. — St. hirsuta, var. atra. We are glad to see 

 this genus preserved entire. — Gnidia denudata, " foliis oblongis quadrifariam 

 imbricatis pilosis trinervibus : nervis denudatis, flori jus terminalibus villo- 

 sis : villis sparsis patentibus." — Allium Cowani, " scapo nudo semiterete, fo- 

 liis lanceolatis acuminatis flaccidis ciliatis vaginanti'.ws, umbella fastigiata, 

 petalis obtusis." From Peru. — Pteurothal/is punctata. — Ponthieva pvtiolata, 

 " spica laxa erecta, foliis petiolatis erectis crispis glabris, floribus discolori- 

 bus :" brought from St. Vincent's by Mr. M'llae.— Po/ygata paniculata. 



Sowerby' s Mineral Conckology. Nos. 75, 76. 



No. 75, PI. 432, &c. Pi/eotui, a new genus of fosiai shells, of which two 

 species are represented, P.plicatus and lavis: the plat J, we observe, is the 

 s.ime that was employed in No. 19 of the Genera of Shells by Mr. G. B. 

 Sowerby : their descriptions are of course somewhat enlarged beyond the 

 limits of a work solely illustrative of Genera. — Turbo conicus, and T.rotun- 

 datiu, from the green sand. — Murex pcnivianus, and HI. tortuosus, crag 

 fossils . the first has a recent analogue in the West Indian seas. 



PI. 434, 435, 436", contain ten species of Tcrebratulae, of which the descrip- 

 tions are promised in No. 76. 



No. 76, PI. 438, &c. TerebratuLe obesa and buccutcnla ; JWytilus edentu- 

 lus, lanceotaius, and sitb/crvis ; Inoceramta cordiformis ; I. C'wt'/m-and Bron- 

 gniurli ; I. mytiloides. These a: - e several species of a remarkable gigantic 

 Genus, formerly considered, from the fibrous structure of its shell, to belong 

 to Pinna: it is peculiar to chalk, and one or two contiguous strata. The 

 reference made by Mr. Sowerby to the mountain limestone seems rather too 

 hasty. — Crenatula ventricosa. Tnis Genus has not before been observed 

 among fossils. 



G. B. Sowerby' s Genera of Recent and Fossil Shells. 



No. XX. of this useful work contains the following Genera : Cardita, 

 united to Vcnericardia ; Cypricardia ; Thecidium, a new genus of Brachio- 

 poda, separated from Terebratula by M. de France, and distinguished from 

 it by the manner of its adhesion, and to which two or three very singular 

 Maestricht fossils belong ; liosletlrtria ; Stroinbus ; and Pleroceras.
