indicus ; P. epiclitum Fischer, from Bos taurus indicus ; and P. scolio- 

 ccdium Fischer, from Buffelus indicus. 



Cestodes from Mammals.* — C. von'Janicki describes Linstowia 

 brasiliensis sp. n. from Didelphys tristriata, Oochoristica bivittata sp. n. 

 from Didelphys murina, 0. ivageneri sp. n. from Myrmecophaga tetra- 

 dactyla, and other new species of Hymenolepis (nine), Davainea (three). 

 He modifies the diagnosis of the genus Anoplocephala Blanchard, and 

 establishes a new genus, Schizotamia, which comes nearest to Bertia in the 

 family Anoplocephalinse. 



Incertae Sedis. 



Anatomy of Ptychodera erythrsea.f — J. W. Spengel gives supple- 

 mentary notes to his earlier work on this species. The details were made 

 out on a young form imperfectly preserved, and embrace points in all 

 the regions of the body. 



Geographical Distribution of Marine Bryozoa.f — M. L. Calvet 

 reviews the evidence bearing on the theory of bi-polarity supplied by a 

 study of a collection of marine Polyzoa from South Patagonia, Tierra del 

 Fuego, and South Georgia. They form an essentially littoral fauna. 

 Those genera in the Austral hemisphere are represented in the Boreal 

 by only 67*3 p.c, while the proportion of species is only 18 '5 p.c. The 

 fauna of the Southern hemisphere has a very local character. The 

 evidence is unfavourable to the theory. 



Jurassic Polyzoa.§ — W. D. Lang concludes that the relationships of 

 the Jurassic forms of the "genera" Stomatopora and Proboscina haVe 

 been misunderstood. A detailed examination of all the material avail- 

 able in the British Museum has resulted in the following conclusions : — ■ 

 The division into these two genera is unnatural. The development of 

 a colony (the zoarium of Polyzoa) is comparable with and follows the 

 same laws as the development of the individual (the zocecium of Polyzoa). 

 Therefore the diagnosis of a form, whether " species " or " circulus," is 

 incomplete, and for practical purposes useless, unless the part of the 

 zoarium with respect to its age is specified. In the " genera " Stomatopora 

 and Proboscina the method of branching is of paramount importance. 

 A re-arrangement in the light of the foregoing is believed to yield an 

 evolutionary series. 



Rotifera. 



New Rotifer. |j — T. E. Lord figures and describes as new Diaschiza 

 crassipes, a species characterised chiefly by a cervical eye, an arched lorica 

 projecting over the foot, with a dorsal cleft widening considerably 

 posteriorly, and two very stout, short, conical toes. The author found 

 only a single specimen, which, having been imperfectly observed, is im- 

 perfectly figured and described.
