" rapid cilia-like action of her feet ; " thus arranging them sat-

GEOPHILID.E Leach. These Myriapods are very long and 

 slender, with from thirty to two hundred segments, each 

 formed of two complete, but unequal subsegments, and bearing 

 but a single pair of feet. There are no ocelli ; the antennae 

 are fourteen-jointed, and the anal feet are short and style-like. 



In Mecistocephalus the " cephalic segment," or anterior part 

 of the head is more than twice as long as broad, while in 

 Oeopliilus the same region of the head is square. 

 M. fulvus Wood is fulvous, polished, with a light 

 orange head ; according to Wood it is most often 

 found under the inner bark of decaying logs of 

 the locust tree. Geopliilus cephalicus is an unu- 

 sually broad species found near Philadelphia. G. 

 bipuncticeps Wood (Fig. 647) is found in the 

 Western States and Sonora. 



In Strigamia the cephalic segment is small, 

 short, and generally somewhat triangular. S. 

 bothriopus Wood is a bright red robust species, and 

 inhabits Philadelphia. S. chionophila Wood is a 

 diminutive species, being only three-fourths of an 

 inch long ; it is found far north, at Fort Simpson, 

 on the Red River of the North. The largest spe- 

 cies known is S. epileptica Wood from Oregon, 

 which is five and a half inches long. The last pair of male 

 feet are represented by Wood to be antenniform, those of the 

 female being small, short, and preserving the usual shape of 

 the leg. This is an interesting instance of the antero- 

 posterior symmetry of these animals, here more strongly 

 marked than usual. 



PAUROPODID.E Lubbock. The sole member of this family is 

 the Pauropus, which Sir John Lubbock discovered in England 

 living among decaying leaves. "The body is composed often 

 segments, including the head, and is convex, with scattered 

 hairs ; there are nine pairs of legs, and the antennae are five- 

 jointed, bifid at the extremity and bearing three long jointed
