♦ Some South African Tardigrada. By J. Murray, 523 



M. echinogenitus Eichters (9). 



The animal found is Eichters' type as found in Spitzbergeu, 

 with the pairs of claws divergent like the letter V, three short rods 

 in each row of pharyngeal tliickenings, and the spines of the egg 

 without areolatiou in the interspaces. The well-developed young 

 was squeezed out of the egg. The pharynx has a " comma " in 

 each row of thickenings, besides the three principal rods. 



3f. arcticm ? Murray {6), plate XVIII. fig. 8. 



This doubtful identification depends on the finding of an egg of 

 the peculiar type of structure of which M. hastatus Murray (5) is 

 the best known example. The rods on the egg surface are most 

 like those of 31. arcticus, but are larger and thicker. 



B. Eggs Smooth, Laid in the Cast Skin. 

 31. nodosus sp. n., plate XVIII. Qa to 6g. 



Specific Characters. — Large, yellow, with large papillose dorsal 

 tubercles in transverse rows, 6 on each segment (see fig. 6f^) and 6 

 on each intermediate false segment. Pharynx with two thick rods 

 in each row, the first twice as long as the second, and no " comma.'' 

 Claws united for a short distance above the base, then divergent, 

 one of each pair longer, and the long claw of one pair longer than 

 that of the other ; long claws with supplementary points. Eggs, 

 elliptical, reddish brown, smooth. Dark eyes. 



Length up to 500 /i, pharynx 50 /z, long. Superficially re- 

 sembling 31. tuherculatus Plate (7), this species differs in nearly 

 all details of structure. It is much larger, and highly coloured, 

 while 31. tiibcrculatus is colourless. The claws of 3f. tuherculatus 

 are widely divergent from the very base, and there are three short 

 equal rods in each row of pharyngeal thickenings. 



The pharynx is of the same type as 31. hufclandii Eichters, but 

 the longer rod is not so clearly double, or formed by the joining 

 end to end of two shorter rods. The basal thickening at the end 

 of the gullet looks more like an expansion of the gullet than 

 separate nuts, and there is no comma. 



The longest claw of each foot has tM'o supplementary points, 

 but two points were not distinguished on the long claw of the 

 lesser pair. 



The stomach is pear-shaped, of few large cells enclosing sienna- 

 brown matter. The coloration of the whole animal is distinctive : 

 yellow skin, salmon-coloured eggs, and brown stomach. 



Cape Colony. Very abundant. Many skins were found with 

 eggs, up to 6 in number, the skins retaining the characteristic 

 tubercles.
