G. roslro corniformi deflexo, dorso carinato, segmentis postice et acute productis. (Saliine.) 



The specimens obtained in Prince Regent's Inlet agreed generally with Captain 

 Sabine's description, but some few, taken at the same time, approached more nearly to 

 Falnicius's * description of Oniscus serratus ; the three posterior pairs of legs being 

 much shorter than those of G. loricatus, but longer in proportion than those of 

 O. serratus, when compared with the third and fourth pairs. In some specimens the 

 rostrum was so veiy minute, as hardly to be distinguishable, whilst in others it was 

 very large. 



It is an abundant species.
