granulis maioribus singulis utrimque supra isthmum ornatae. 

 Lobi laterales semicellularum margine granulis 3 acutiusculis 

 armatae; lobi polares apice excavata, angulis spinigeris, 

 marginibus lateralibus infra spinam leniter prominentibus. 

 A latere visum percrassum apice latissime rotundata, tumo- 

 ribus centralibus et granulis utrimque ad isthmum conspicue 

 prominentibus. Long. 25, lat. 20, crass. 14,5, isthm. 5,3 u. 

 [N:o 1012 et 1126]. 



Though considerably differing from the type in the 

 arrangement of the granules, I believe this form should 

 best be referred to this species, the general outline of the 

 cells being almost the same. Compare also E. denticulatum 

 (K i r c h n.) Gay and E. subrostratum West.

Eu. pseudoboldtii, nov. sp. Cellulae parvae; semicel- 

 lulae subquadratae lobis lateralibus aequaliter bidentatis; 

 lobo polari apice medio retusa, conspicue dilatato, angulis 

 non rostratis sed mucronatis; inferius sinu profundo a lobis 

 lateralibus dissecto. Membrana in tumore centrali glabra, 

 sed inferius supra isthmum granulis binis ornata; ceterum 

 margines versus granulis nonnullis et utrimque sub impres- 

 sionem apicalem granulis binis maioribus ornata. A vertice 

 visae subovales polis non rotundatis, medio utrimque pro- 

 minentia depressa. A latere visae subrectangulares apice 

 crassa subrecta. Long. 22,4, lat. 16, s, crass. 9,9, isthm. 3,9/'.

This species is probably nearest to E. boldtii S c h m. 

 But I think it is quite sufficiently characterized by the late- 

 ral lobes, which are equally bidentate, whereas the lateral 

 lobes of E. boldtii are rounded and acutely tridentate; 

 likewise the deep sinus between polar- and lateral lobes is 

 a very distinctive feature; the central protuberance is not 

 so prominent and quite smooth.
