APPENDIX. No. IV. 411 



Genus III. Loligo. The characters presented by three new species, are very 

 different from those observed in the LoUgines of the European seas. The 

 distal Suckers of the larger or supplementary arms, are produced into hooked 

 processes, and in two of them all the suckers of the shorter arms are formed in 

 the same manner.* 



Sp. 1. Loligo Banksii. Shorter ai-ms with globose simple suckers, the fins 

 forming, by their union, a rhomboidal figure. 



Obs. The colour of this, when alive, is pale flesh. The body is ycUowish 

 behind, sprinkled irregularly with blackish spots teinted with purple. 

 The external aspect of the arms is freckled witli purplish. The under 

 parts of the fins without spots. One specimen was taken in the Gulph 

 of Guinea. 

 Sp- 2. Loligo Icptura. Shorter arms with hooks on their suckers, longer arms 

 with free hooks on the distal suckers, tail abrupt and slender. 



Obs. Tlic body and external aspects of the arms are smooth, with a few 



tubercles arranged into longitudinal lines. Two were taken in 1, 8, 



N. lat. 7, 26, 30 E. long. 



Sp. 3. Loligo Smithii- Shorter arras with hooks on their suckers, larger arms 



^vith the hooks of the distal suckers furnished anteriorly wiili a membrane, 



tail gradually attenuated. 



Obs. Body and arms externally tuberculated ; the tubercles purple with 

 white Ups, and arranged into longitudinal lines. 



PXEROPODA.f 



Of this division of the molluscous tribe of animals, two species of Peron's 

 genus Cleodora were taken in south lat. 2, 14, E. long. 9, 55, 15, and S. 



* Id the museum of the College of Surgeons is preserved part of the arm of a large 

 and unknown animal of this class, in which the suckers are all furnished with distinct 

 strong and free hooks. 



+ Of the genns Firola (whose sitnation has not yet been satisfactorily ascertained, 

 hut which, with Cuvier, I ara disposed to consider as more nearly allied to the Gastk- 

 ROPOOA, than to any other class) a new species was found iu S. lat. 3, 15, 0, £. long. 

 9, 38, 0, viz. Firola arcuata. Dorsal fin simple, vermiform appendage none, tail arched 

 above, without any vermiform appendage. Two other species were sketched by Lieut. 

 Hawkey, but were not received.
