ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 393 



species from mammals, birds, reptiles, amphibians, and tishes. Three 

 new genera are established, Microhrema, Leptolecithum and Exorclm. 



J. A. T. 

 Larval Flukes from Georgia. — Ernest Careoll Faust {Trans. 

 Amer. Micr. Soc, 1921, 40, 4'J-r)5, 2 pis.). A description of a number of 

 new forms of cercaria from the snails Goniohasis carinifera and Ancidosa 

 carinata. They are all Distomes and show interesting relations to 

 previously described forms. J. A. T. 



Life-cycle of Echinostoma revolutum. — John C. Johnson (Univ. 

 California Publications Zoology, 1920, 19, 835-88, 7 pis., 1 fig.). The 

 stages in the life-history of this Trematode are described in detail 

 — egg, miracidium, mother-redia, daughter-redia, cercaria, encysted 

 agamodistome, and adult. Two hosts are necessary, the snail Pkysa 

 occidental is and a duck or goose. Apparently any duck or goose forms 

 a suitable host. J. A. T. 



Tapeworms of Poultry. — F. J. Meggitt {Parasitology, 1920, 12, 

 301-9, 2 pis., 1 fig.). Descriptions of Cotugnia digonopliora (Pasquale, 

 1890) from chickens, G. fastigiata sp. n. from domestic ducks, 

 Hymenohpis columbse (Zeder, 1800) from pigeons, H. coronula (Dujardin, 

 1845) from ducks, and H. gracilis (Zeder, 1803) also from ducks. 



J.A.T. 



New Cestode in Hedgehog. — F. J. Meggitt {Parasitology, 1920, 

 12, 310-3, 1 pi.). Description of Oochoristica erinacei sp. n., and a 

 key to the genus. Five other Cestodes have been recorded from the 

 hedgehog. From all of these this new species is distinguished by its 

 possession of numerous testes, situated posteriorly to the female organs. 



J.A.T. 



New Tapeworms from Ostrich.— F. J. Meggitt {Parasitology, 

 1921, 13, 1-24, 1 pi., 2 figs.). Descriptions of Dcwainea bedclardi sp. n. 

 and D. linstowi sp. n. ; a revision of the genus Davainea and a key to 

 the species ; a list of species of Davainea with their hosts. The species 

 fall roughly into four groups, the division being based upon the armature 

 of the suckers and the position of the genital pores. J. A. T. 



Echinodsrma. 



Locomotion of Stichopus panimensis. — G. H. Parker {Journ. 

 Exper. Zool., 1921, 33, 205-8, 1 fig.). This Holothurian creeps on 

 its trivium by means of locomotor waves of a direct monotaxic type. 

 These waves progress over the animal at a rate of about 0*39 cm. per 

 second, and they enable the animal to creep a metre in about a quarter 

 of an hour. The part of the trivium moved forward is lifted well above 

 the substratum to which the remainder of the trivium is attached by 

 the tube-feet. J. A. T. 



Reversal of Asymmetry in Plutei of Echinus miliaris. — Hiroshi 

 Ohshi.aia {Proc. Roy. Soc. London, 1921, 92, 1G8-78). Description of 

 a number of abnormal plutei which had the hydrocoele developed on the 



2 E
