8l8 ORDER TENTACULIFERA-SUCTORIA. 



B. — Tentacles fasciculate. 

 Podophrya carcliesii, C. &: L. Pl. XLVIII. Fig. 23. 



Body subspheroidal, ovate, or irregular in shape, the distal or anterior 

 extremity rounded, bearing on one side a single fascicle of tubular suckers ; 

 pedicle as short as, or shorter than one-half the length of the body, usually 

 asymmetrically inserted ; contractile vesicle single, situated near the anterior 

 extremity. Length of body 1-950" to 1-350". 



Hab. — Fresh water, usually attached in social colonies to the stalks 

 of Carchesium polypinum. 



The author obtained examples of this t)'pe developed in great abundance on 

 the branching pedicle or ^oodendrium of Epis/ylis Jiavicans, remitted from the 

 neighbourhood of Stourbridge, Worcestershire, by Mr. Thos. Bolton, in April 1874. 



Podophrya cyclopum, C. & L. Pl. XLVL Fig. 23. 



Body ovate or globular, tapering posteriorly, the anterior extremity 

 rounded or lobate, bearing from two to four fascicles of capitate suckers ; 

 pedicle usually very short, rarely exceeding one-third of the length of the 

 body ; contractile vesicles one or two in number ; endoplast oval. Length 

 of body i-Soo" to 1-300". 



Hab. — Fresh water, mostly parasitic on Cyclops quadricornis and other 

 Entomostraca, but occasionally on aquatic plants. 



This species was originally figured and described by Stein under the title of 

 " Acinde der Cyclopm" being at that time regarded by him as the embryonic form 

 of some higher ciliate animalcule. 



Podophrya Leichtensteinii, C. & L. 



Body ovate or pyriform ; tentacles slender, not distinctly capitate, 

 forming two antero-lateral fascicles ; pedicle about one-half the length of 

 the body, widely expanded at the point of junction with the latter, tapering 

 posteriorly, transversely wrinkled ; endoplast oval, subcentral. Length 

 1-300". Hab. — Fresh water, on aquatic Coleoptera. 



This species, first described by Stein as the Acineta-phase of Operadaria Leich- 

 tenstdnii, subsequently received from him the title of Acineta hyphydri. Clapar^de 

 and Lachmann had, however, in the interim conferred upon it the name above 

 given, and which necessarily takes the precedence. 



Podophrya phryganidarum, Stein sp. 



Body pear-shaped, flexible, slender and tapering somewhat abruptly 

 posteriorly ; pedicle about half the length of the body, more or less curved, 

 narrowest at its point of attachment, increasing slightly in diameter as it 

 approaches its point of union with the body, finely striate longitudinally ; 

 tentacles long and fine, not distinctly capitate, forming t\vo antero-lateral 

 fascicles ; contractile vesicle single, anteriorly situated ; endoplast elongate- 

 ovate or band-shaped. Length of body 1-240".
