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

 scribed, the Squilla ciliata, Fabr., {Squilla stt/lifera, Lara.), 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 spinifrons; and in illustration of the distinctions between it 

 and the Fabrician species the following characters were read by 

 Mr. Owen : 



* Antenna chelis breviores. 

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

 prceter segmentis natatoriis,lcem ; rostro inermi ; segmento ultimo 

 superne 5-carinato. 

 Hab. Oahu. 



** Antenna chelis longiores. 

 Squilla spinifrons. Squil. pollice tridentato; corpore suprh, 

 prater segmentis natatoriis, Icevi ; rostro 3-spinoso ; segmento 

 ultimo superne 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. Chiragra, Ejusd., for which the following 

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

 distinguishing it from Gon, ensiger. 



Gonodactylus Chiraora, Latr. Gon. pollice edentato, basi 

 extus gibbo, intus crenato ; rostro 3-spinoso, spina intermedia 

 productd. 

 Long. 4 unc. 



Hab. "in insula Erromanga Novarum Hebridum Oceani Pacifici, 

 ubi in foraminibus rupium se celat," teste Dom. Georgio Bennett. 

 Gonodactylus ensiger. Gon. pollice edentato, ensato, intus 



acuto; rostro 3-spinoso, spina intermedia obsoletu. 

 Long. 6 unc. 

 Hab. Valparaiso. 

 Color flavus; chelarum cceruleus. 



Prflecedenti valde affinis, praesertim sculptura armaturaque seg- 

 mentorum ultimorum ; sed diftert pollice ad basin non ventricoso, 

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

 ducts ; necnon magnitudine. 



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

 Squilla spinifrons. 



Specimens were exhibited of several Humming Birds from Po- 

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

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

 were read. 



Trochilus tyrianthinus. Troch. capite supra dorsoque aureo- 

 viridibus ; guld splendenti saturate viridi ; alis brunneo-Juscis ; 

 caudd subrotundatd, latissima, aureo-purpurea : rostro gracili, 

 brevissimo, recto. 

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