spine on the inner side of the propodite, at the point of articulation with the 
dactylus, and two pairs of spines on the dorsal side of the telson. These 
points are not specified in Kingsley’s description. The rostrum is acute, its 
margins ciliated ; it exceeds the orbital spines, reaching forward beyond the 
middle of the first segment of the antennule. 
In a later paper * Kingsley says that A. panamensis may prove to be the 
same as A. spinifrons M. Edw.,t from the coast of Chile. But Milne Edwards 
states that the smaller chela of A. spimfrons is extremely short, while in 
A. panamensis it is described as being nearly as long as the larger chela ; in 
A. spinifrons the antennal scale is very small, while in A. panamensis it ex- 
tends slightly beyond the peduncles of the antennules. If the “ Albatross” 
specimens are correctly referred to A. panamenis, this species is further dis- 
tinguished from A. spinifrons by the form of the front, which in the latter 
species is described as inclined and armed with three spines (the rostral and 
two ocular) of equal length, while in the specimens before me the rostrum 
is much longer than the ocular spines.
