median line outwards. The rudimentary fourth lobe is more 

 or less developed. The first three pairs of lobes have each two 

 notches on the outer edge and one or two on the inner edge. 

 The marginal gland pores are found as in zizyphus, except that 

 there is only one between the third and fourth lobes, while in 

 zizyphus there are two. The chitinized disks of the marginal 

 glands are present though not very prominent. The plates are 

 unusually narrow and long ; the incisions are not deep, and 

 average about three or four in number. There are no dorsal 

 glands like those in zizyphus to be found in the pygidium, but 

 there are, according to Green (1899), and indistinctly seen in 

 specimens observed, minute circular glands arranged in a row 

 cephalad of the second lobe.

Proteus has four groups of circumgenital glands. There are 

 three pairs of well-developed lobes. The rudimentary fourth 

 lobe is absent and in its place is found a plate. The lobes are 

 trilobate in form. The marginal-gland orifices are as in zizy- 

 phun. The position of the dorsal glands, however, differs from 

 that in zizyphus, there being no median dorsal gland. Neither 

 is the pair of glands mentioned as characteristic in the descrip- 

 tion of zizyphus found in proteus. The glands are also fewer in 

 number. There is a pair of glands cephalad of the first pair of 

 lobes, a single gland cephalad of the third marginal gland or 

 the third lobe ; then come numerous glands whose arrangement 

 seems to be less constant.
