and the forms just described probably have many connections with 

 Protomyxomyces coprinarius Cunningham. 



Class Sporozoa. — Some specimens of a probably new species of 

 Coccidium, resembling C. Bivolta, were found in a Coronella, and are 

 perhaps identical with a form found in the toad. 



A Moneran from the blood of Hyla viridis, having obtuse motile 

 radiating filaments, is perhaps connected with the organism of the 

 blood of subjects afflicted with palustric fevers (Laveran). Of two 

 forms of corpuscles found in human faeces, the larger has hyaline 

 contents, including small shining yellowish rods, and is perhaps 

 connected with the Coccidia ; the smaller, which occurs also in cow- 

 dung, is perhaps, an Amoeba rendered immobile by lowness of tem- 

 perature. 



Studies on the Gregarinida.* — A. Schneider forms a new genus . 

 Lophorhynchus for L. insignis which was found in the digestive tube 

 of Relojps striatus. Allied to Stylorhynchus, it is distinguished by the 

 characters of its organ of attachment ; there is a subsessile rostrum 

 attached by a wide base to the protomerite, and the actinophore is 

 formed by a membranous expansion, which is depressed in the centre. 

 TrichorJiynchus is another new genus, formed from T. insignis found 

 in the digestive tube of Scutigera, and distinguished from Stylo- 

 rhynchus by the characters of its spores, which are never united into 

 bands. The author also describes Gamocystis francisci n. sp., found 

 in the digestive tubes of the larvee of the Ephemeridaa ; Hyalospora 

 affinis, n. sp., from the intestine of Machilus cylindrica ; and a new 

 genus Cnemidospora, for G. lutea, from the digestive tube of Glomeris. 

 This is remarkable for the characters of its protomerite, the contents 

 of which are formed by two masses, distinguishable by various 

 characters. The lower has finely granular, the upper highly refrac- 

 tive, and, apparently, fatty contents, and is of greenish, and not, as 

 the other, of a yellow or brown colour.

Morphology of the Embryo.f — E. Warming describes the embryo 

 of Avicennia as entirely devoid of radicle, like that of Utricularia, 

 Bappia, and some other plants. The author disputes the ordinary 

 view that the suspensor is altogether a distinct organ from the 

 embryo itself. In some plants, as Pistia, Gypripedium, Lisfera, 

 Epipactis, TropcBolum, &c., the suspensor is altogether wanting ; 

 when present, although its physiological value is distinct, viz. to carry 

 nutriment to the embryo, Warming is unable to detect any morpho- 

 logical difference between the two ; it is simply the lower portion
