unarmed. Of tliis section but one species liad be6n previously de- 

 scribed, the Sguilla ciliata, Fabr., (Scuilla stylįfera, Lam.), a figure 

 of which has been engraved for the forthcoming Appendix contain- 

 ing theZoology of CaptainBeechey's late ' Voyage to the South 

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

 Sguilla spinifrons; and in illustration of the distinctions between it 

 and the Fabrician species the following characters vvere read by 

 Mr. Owen : 



* AntenncB clielis breviores. 

 Squilla ciliata, Fabr. Squil. pollice tridentato į corpore supr^, 

 prceter segmeniis natatoriis, Icevi į rostro inermi ; segmento ultimo 

 superne 5-carinato.

 Squilla spinifrons. Sguil. pollice tridentato; corpore svpr a, 

 prceter segmentis natatoriis, tavi; rostro 2-spinoso; segmento

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

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



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

 nearly allied to Gon. Chiragra, Ejusd., for vvhich the foUovving 

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

 distinguishing it from Gon. ensiger.

 eztiis gibbo, intiis crenato ; rostro 3-spinoso, spina intermedia 

 prodiccta.

Mr. Cuming statės that this is taken in the šame manner as the 

 Sguilla spinifrons.

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