Definition: “Species of Callianassa with the maxillipeds 
of the third pair very broad, a lobe on the hinder edge of 
the propodite on the legs of the third pair, the endopodite of 
the last limb broad and square-ended, and the telson as long 
as, usually longer than, it is broad, almost or quite as long 
as the endopodites of the last pair of limbs.”

Subgenus CaLiicuirvs f, Stimps., 1866. 
Definition : “‘ Species of Callianussa with the maxillipeds 
of the third pair usually narrow as compared with those of 
Trypea, a lobe on the hinder edge of the propodite in the 
characters of this subgenus, but seems, by the hook on its arm, to be 
near the ancestor which gave rise to Tryp@a, where this is a common 
feature. 
* Doubly preoccupied, first by Stimpson in 1856 as a synonym for 
C. californica, Dana, and later by Bate himself in 1888. 
+ According to the recognized rules of zoological nomenclature (for 
instance, by Art. V. 5, of the Code of Rules adopted by the last Zoolo- 
gical Congress), this name must be given to the subgenus before us, 
although the most striking feature of Dana’s 77yp@a—the extreme short- 
ness of the antennular flagella—is not characteristic of it as now consti- 
tuted. C. australiensis must remain the type species, although C. wnci- 
nata or C. gigas would have been more suitable. 
{ Callichirus becomes the name and C. major the type of this sub- 
genus by the same rule that makes Trypea the name and C-. australensis 
the type of the foregoing one. C. brevicaudata would probably be a 
better type.
