ANALYSIS OF PEIIIODICAL AVOKKS ON ZOOLOGY AND BOTANY. 



S'jsai/ison's Zoological Illustrations. No. 27. 



PL 130 and 131 illustrate, in the ir.ost conipletc manner, 

 that remarkable bird Trocliilns latipennis^ or Broad-shafted 

 Humming Bird of Latham, Avhich is here called the Gray 

 sickle-winced Humming Bird, for the sake of distinguishing 

 It irom two other species, both iscith hroad shajts to their wings, 

 first described by Mr. Swainson in this work : both sexes are 

 figured ; from which it appears the quill-feathers in the female 

 are similar to tiiose usual in the birils of this genus. PI. 1 32. Ma- 

 aoglossnm ajintdosum and fasciafimi, two new irisects from Bra- 

 zil, thus characterized : M. aiinnlosimi ,- alls nigris, anticis fas- 

 ciis 2 hyaline maculatis ornatis; abdominis nigri, segmento 

 tertio niveo. M. fasciatiim ,- alis nigricantibiis, anticis fusco 

 variis, posticis striga aurantiaca centrali ornatis ; thorace 

 grisea ; corporis lateribus, maculis aurantiacis, nigris et pal- 

 lide fulvis insignibus ; antennis gracilibus unco producto. 

 PI. 133. Another new and interesting lepidopterous insect, 

 likewise from Brazil. Thccla macaria, with figures of both 

 the sexes ; T. alis supra fuscis, anticis ad basin ca2ruleis, infra 

 ferrugineis, punctis 2 mediis nigris ornatis; posticis infra cas- 

 taneis, antice pallidioribus, macula nigra ad basin ornatis. 

 PI. IS^ beautifully rejnesents Slromhtis Icntiginoms, and a 

 new species by the name of exusfi/s, nearly apjjroaching to it, 

 but thoroughly distinguished b\' these characters : " S. testa 

 nodosa, labio interiore albo, laevi ; labii exterioris inflexi, su- 

 pra sinuati, intus })urpureo-atri, striali, lobo basali edentulo." 



Soxverfji/'s Genera of Shells. No. 9. 



Two Plates accompany th.e description of the genus Spon- 

 DYi. us, of which the definition (although a))parently correct) is 

 loaded with unnecessary detail, occupying nearly half a page, 

 although its essential characters iriight have l)cen contained in 

 eight or ten lines. AMPHinr.SMA, a genus possessing at the best 

 butdubiouscharacters. Slccinea of Draparnaud. accompanied 

 by excellent figures. Mr. Sowerby judiciously adopts tliis gomis 

 after the best c<mtinental conchologists, in )ireferencc to M. de 

 Ferrussac. Indeed we have been greatly dis!ip})ointed in the 

 systematic arrangement of the land sliclls projiosed i)y this last- 

 mentioned author. With facilities for investigating tlicm in the 

 most peiiect manner, we had exj)ec(ed something beyond a 

 mere artificial arrangement of divisions " ten times divided," 

 and a whole list of new flimily names, more jK'i-j)lexing tlinn
