Extract

It would appear from the data presented that the favourite location for the common rat fleas of this vicinity, Ceratophyllus fasciatus, Bosc., and Loemopsylla cheopis, Roth., is about the hind quarters of the rat, while Ctenopsyllus musculi (Dugès), Wagner, prefers the region of the head and neck.

The same regional distribution of rat fleas was found in the case of the guinea-pigs.

Squirrel fleas are most numerous on the hind quarters.

These observations, while they are not to be insisted upon as throwing any special light upon the regional distribution of buboes in naturally infected plague rats, are of particular interest in showing the very constant preference of Ct. musculi for the region of the head and neck.

In regard to the other species of fleas it should be borne in mind that the skin areas are not of equal dimensions; that of the head and neck being smallest; that of the hind quarters being the largest; and the skin area of the fore quarters being between these in size.
