Leydigia acanthocercoides, G. O. Sårs. 'On some South 

 African Entomostraca raised from dried mud.' Chr. Vid. 

 Selsk. Forh. 1895, p. 18, Pl. 4, figs. 1—4 (not Fischer). 



Remarlvs. — Having now, through the kindness of 

 Prof. Lilljeborg, had an opportunity of examining Swedish 

 specimens of the true L. acanthocercoides Fischer, I find 

 that the South African form described by me under this 

 name is in reahty specifically distinct, for which reason I 

 propose for it the above name. It differs not only in the 

 shape and sculpture of the carapace, but also in the much 

 smaller size of the ocellus, which scarcely exceeds that of 

 the eye, w^hereas in L. acanthocercoides it is considerably 

 larger. Moreover the caudal part is somewhat less broad, 

 and the terminal claws have each at the base a very small 

 denticle, omitted in my previous figure. 



Occurrence. — Two well preserved female specimens, 

 exactly agreeing with the South African form, were found 

 in the sample taken in Sumatra by Mr. Iversen. To show 

 the identity, I give on the accompanying plate an habitus- 

 figure (side-view) of one of the specimens and a somewhat 

 more strongly magnified figure of the caudal part from the 

 same individual. 



Distribution. — Knysna (Cape Colony). 



15. Aloiia tenuicaiidis, G. O. S ars. 

 Occurrence. — This form developed in several of my 

 aquaria prepared with mud from Sumatra. 



Distribution. — Europe, Central Asia, Algeria.
