 includes " Phalanpium Balienarum, die 9I>a((jl^c()IauS. P. abdomine dilatato muricato, 

 rostro subulato. Pennant's British Zoology. P. iv. tab. 18. fig. 7." In Suborder B, Crus- 

 tacea, he gives Cancer divided into three Families, Brachyuri, Parasitici, Macrouri, the first 

 with six, the second with one, the third with eight species. The 1 4th species is thus given : —

 dans le departement du Calvados, lu a la seance du 14 mars 1825 ; Par M. De

In the introduction de Brebisson promises a similar work " sur la classo des Arachnides et sur 

 celle des Insectes," if the years which are accumulating so rapidly on his head, leave him 

 time for it. This seems an odd expression for a man of twenty-seven, which would be his 

 age at this time according to the date of his bii'th given by Hagen. Further on, in treating 

 of the difficulties of obtaining specimens of marine Crustacea, he says, " En effet, comment 

 parvenir h. connaitre celles dont I'existence semble etre confinee aux plus grandes pro- 

 fondeurs de rOcoan 1 " To this question the Challenger and similar expeditions have at 

 least begun the answer. 



In " Ordre 3, les Ampbipodes. Ampliipoda" he gives, with short descriptions of the genera and 

 species, Gammarus pulex, Fab. Lat. etc.; Talitrus loeusta, Lat. Lamk. ; Talitrus gam- 

 mar ellus, Lat. Lamk., Bosc, etc., the species now generally accepted as Orchestia gammarellus ; 

 Mclita palmata, Montagu, sp. : CoropMurn longicorne, Lat. Lamk. 



"Order 4. Les Isopodes. Isopjoda," begins with ChevroUe, Gapreola, Lat. Lamk., Caprella being 

 intended. The species given is " C. Linearis. Lat. {C. Seolopendroides. Lamk. — Cancer. 

 Lin.)." Then follow Anceiis, Eisso, Jo7ie, Leach, Sphseroma, Lat., &c.
