The pattern of the plates is close and regular, and the dots 

 appear to be depressions. The five lateral processes agree with 

 E. victor Ehr. {2), but the proportional sizes of the processes are 

 different, and there is only one dorsal process on each side instead 

 of two. Professor Eichters {11) describes, without naming or 

 figuring, an almost exactly similar species. 



MiLNESIUM. 



M. tardigradum Doy. {1). 



In Scotland the shorter claws of this species are variable, 

 having from one to three points on each. All the African 

 examples seen had three points on the shorter claws of all legs. 



One skin contained three eggs. 

 • Cape Colony. Only a few examples. 



Maceobiotus. 



§ 



The genus is divided into sections according to the characters 

 of the eggs, which are either spiny, in which case they are laid free, 

 or smooth, and are then laid several together in the skin when 

 it is cast. A few of the spiny eggs have the rods imbedded in a 

 clear matrix. Examples of all three kinds are among the African 

 species. 



The pharynx contains several rows of hard bodies (3 double 

 rows) referred to as rods or nuts. The number of these free rods 

 is always either two or three, exclusive of a short process at the 

 anterior end of each row, which appears to be joined to the gullet, 

 and another small nut at the posterior end of each row, which Pro- 

 fessor Eichter calls a " comma." The anterior nut is rarely or 

 never absent, but many species have no " comma." 



A. Eggs Spint, Laid Feee. 

 M. hufelandii (Eichters) {9) {10). 



Diverse animals have been identified by various authors as 

 Schultze's M. Imfelandii {13). The species found in South Africa 

 is that referred to under this name in Professor Eichter's various 

 works, and which I have followed him in recording from different 

 parts of the world under the same name. It has the claws of each 

 pair united about half-way up, the pharynx with a nut, a long 

 double rod, a shorter rod, and a " comma " in each row of thicken- 

 ings. The egg has processes which are conical in the lower 

 portion, and expanded above into a disk. It is a well-marked 

 species, accurately characterised by Professor Eichters, though its 

 identity with Schultze's species may be questioned, the description 

 of that species being, like most of the early descriptions, rather 

 inadequate.
