unarmed. Of this section but one species had been previously de- 

 scribed, the Squilla ciliata, Fabr., [Squilla stylifera. Lam.), a figure 

 of which has been engraved for the forthcoming Appendix contain- 

 ing the Zoology of Captain Beechey's late 'Voyage to the South 

 Pacific/ &c. The second species was described under the name of 

 Squilla spin'ifrons ; and in illustration of the distinctions between it 

 and the Fabrician species the following characters were read by 

 Mr. Owen : 



* AntenncB chelis breviores. 

 Squilla ciliata, Fabr. Squil. pollice tridentato ; corpore stipra, 

 prci'ter segmentis natatoriis,la:vi ; rostro inermi; segmento ultimo 

 supente 5-carinato. 

 Hab. Oahu. 



** Antennce chelis longiores. 

 Squilla spiNiFRONs. Squil. jjollice tridentato; corpore supra, 

 pra;ter segmentis natatoriis, laevi ; rostro 3-spinoso ; segmento 

 ultimo sujjcrne 1 1 -carinato. 

 Hab. Valparaiso. 



Mr. Cuming's note affixed to the latter states that it was " caught 

 by dredging in deep water, and by the fishermen's lines." 



The other new species is referable to Gonodactylus, Latr., and is 

 nearly allied to Gon. Chiragrn, Ejusd., for which the following 

 amended character was proposed by Mr. Owen with the view of 

 distinguishing it from Gon. ensiger. 



Gonodactylus Chihagra, Latr. Gon. pollice edentato, basi 

 extiis gibbo, intus crenato ; rostro S-spinoso, spina intermedia 

 product a. 

 Long. 4 unc. 



Hab. "in insula Erromanga Novarum Hebridum Oceani Pacifici, 

 ubi in foraminibus rupium se celat/' teste Dom. Georgio Bennett. 

 Gonodactylus ensiger. Go7i. pollice edentato, ensato, intus 



acuto ; rostro 3-spinoso, spina intermedia obsoletu. 

 Long. 6 unc. 

 Hab. Valparaiso, 



Color flavus; chelarum coeruleus. 



Prfficedenti valde affinis, praesertim sculptura armaturaque seg- 

 mentorum ultimorum ; sed dift'ert pollice ad basin non ventricoso, 

 ad marginem internum non crenato ; spina rostri media non pro- 

 ducta ; necnon magnitudine, 



Mr. Cuming states that this is taken in the same manner as the 

 Squilla spinijrons. 



Specimens were exhibited of several Humming Birds from Po- 

 payan, forming part of the collection of Mr. John Gould; and tlie 

 following characters;, by Mr. George Loddiges, of four new species 

 were read. 



^ Trocpiilus TYRiANTHiNus. TrocJi. capite supra dorsoque aureo- 

 viridibus ; guld splendenti snturcde viridi ; alis brunneo-Jiiscis ; 

 caudd subrotundatd, latissitnd, aureo-purpured : rostro gracili, 

 brevissimo, recto. 

 Long, corporis, 4 unc. ; rostri, 4 lin.
