Specimens were exhibited of several Stomapodous Crustacea, also 

 from the collection of Mr. Cuming, a collection extremely rich in 

 Crustacea, Mollusca, and other invertebrate animals inhabiting the 

 sea. A considerable portion of it was formed during a voyage in 

 the Southern Pacific Ocean undertaken by Mr. Cuming in a vessel 

 freighted by him for the express purpose of obtaining objects of 

 natural history. Among those now exhibited Mr. Owen pointed 

 out two new species, one of which belongs to that section of the 

 genus Squilla, Fabr., which is distinguished by the presence of 

 moveable spines at the extremity of the caudal segment, and like- 

 wise, as was particularly shown, by the first pair oi pcdipalpi being 

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

 scribed, the Squilla ciliata, Fabr., [Squilla stijlifera. 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 spinifrons ; and in illustration of the distinctions between it 

 and the Fabrician species the following characters were read by 

 Mr. Owen : 



* Antennce clielis breviores. 

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

 prceter segmentis natatoriis,la:vi ; rostro inermi ; segynento idlimo 

 supeme 5-carinato.

** Antenna: ckelis longiores.

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

 ultimo supeme 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 Goiiodacfylus, Latr., and is 

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

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

 distinguishing it from Gon. ensiger.
