GENUS VAGINICOLA. 717 



prolonged towards the somewhat uneven anterior border ; the extended 

 body projecting but slightly beyond the aperture of the lorica ; peristome- 

 border thickened ; ciliary disc obliquely elevated ; endoplast cord-like, 

 convolute. Dimensions unrecorded. Hab, — Fresh water. 

 Figured and described by D'Udekem as a species of CotJmrnia. 



Vaginicola ingenita, From. sp. 



Lorica very short, only one and a half times as long as broad, narrow 

 at the aperture, inflated posteriorly ; body transparent, granular, very 

 elastic, extending considerably beyond the aperture of the lorica. Length 

 of lorica 1-400". Hab, — Fresh water. 



Identical with the Planicola ingenita of De Fromentel.* 



Vaginicola attenuata, From. sp. 



Lorica subcylindrical, sharply and abruptly attenuate towards its point 

 of attachment, truncate and not everted anteriorly, about twice as long 

 as broad ; animalcule small, protruding but little beyond the aperture of 

 the lorica, urn-shaped when contracted. Length of lorica 1-300". 



Hab. — Fresh water. 



Vaginicola vestita, From. sp. 



Lorica vase-shaped, twice as long as broad, the anterior border narrow, 

 bulging posteriorly, but rapidly tapering again towards its point of attach- 

 ment, the upper two-thirds transparent, colourless, the lower one brown and 

 opaque ; animalcule trumpet-shaped when extended, protruding to a mode- 

 rate extent beyond the aperture of the lorica. Length of lorica 1-400". 



Hab. — Fresh water. 



The two colours of the lorica of this animalcule, referred to the genus Planicola 

 by De Fromentel, form a very remarkable feature. Its discoverer does not, how- 

 ever, say whether many specimens were encountered exhibiting a hke peculiarity, 

 a circumstance which leaves it open to conjecture whether the upper transparent 

 portion of the lorica may not possibly represent a repaired portion or even the 

 newly formed lorica of a young individual built up from the fragmentary basal portion 

 of a deserted test. In other respects the aspect of this type coincides closely with 

 that of D'Udekem's Vaginicola globosa. 



Vaginicola inclinata, From. sp. 



Lorica transparent, subcylindrical, rounded and widest posteriorly, 

 nearly three times as long as broad, never fixed perpendicularly to, but 

 deviating at a sharp angle from its base of attachment ; body transparent, 

 granular, trumpet-shaped, extending for nearly half its length beyond the 

 aperture of the lorica. Length of lorica 1-500". Hab. — Fresh water. 



Included by De Fromentel in the genus Planicola.
