The Head Louse, drawn above, is not very unlike a long bed- bug {Ciniex) in its early stage. The lice without suckers, and with jaws that can bite through the skin, afflict most domestic mammals and all sorts of birds. In tracing their development within the ^^^ it becomes evident that some of the earlier characters of the embryo are retained per- sistently ; thus the permanently enlarged forehead of the bird louse can be recognised during very early ^g^ life, but this structure disappears very soon in the embryos of the true lice with suckers. The legs and claws of the different species of Philopterous or bird lice vary much in structure, on account of the peculiar con- ditions in which the parasites are placed and live. One genus, which has a species parasitic on the porpoise—the only marine.
