organisms, he details the effects of strychnin, antipyrin, cocain, anti- 
f ebrin, and chloralhydrate, exhibiting the results in each case in a tabular 
form. 
Meunier finds nitrogenous matter in nummulitic rocks from Biarritz, 
which he therefore considers to contain an organic basis comparable to 
carbonaceous combustibles of vegetable origin. 
The tentacles of Suctoria do not, as Hertwig supposes, play an active 
part in absorbing the prey. They are passive in the operation, and often 
remain quite motionless. The protoplasm of the body furnishes the real 
motive power, which is connected with the action of the contractile 
vacuoles. These are now known to be excretory in function. Their 
pumping motion induces a stream towards the interior of the animal, and 
is the real cause of suction. Eismond (1).

V.— CLASSIFICATION. 
Borgert proposes to establish a special order of the Mastigopliora to 
receive the Dictgochidce. These forms are clearly separated from the 
Radiolaria by the absence of pseudopodia, and the occurrence of conjuga- 
tion. A flagellum is present, but the siliceous skeleton distinguishes the 
group from other Flagellata. The name Silicoflagellata is suggested. 
Hertwig and Haeckel are mistaken in considering their tests isolated 
skeletal parts of Phceodaria. They are independent organisms.

For Monadina from the G. of Naples, see de Bruyne. 
Burrows treats of the red chalk Foraminifera from certain English 
localities. 
For Scotch palaeozoic Radiolaria see Hinde. 
For Sicilian, Dreyer (1). 
Franzenau gives an account of some Hungarian Foraminifera . 
For deep-sea Foraminifera from the Irish coast, see Wright. 
Halkyard gives a list of 127 species and varieties of Foraminifera 
collected at Jersey. 35 genera and 8 families are represented. The 
Rotalidai appear to be most numerous. Certain common British species, 
e.g.y Orbulina universa, are entirely absent. 
Immof (1) concludes his list of the pelagic fauna of the mountain lakes 
of Carinthia. The Flagellata are represented by 3 species. Dinobnjon 
divergens in six lakes, D. elongatum in two, and D. biitschlii in one. 
They were found in colonies, but not at the time of observation (July, 
August, and September) in such colossal numbers as always occur in 
spring and early summer. The Dinoflagellata were represented by Cera -
