t^^on, a new provisional and anomalous genu.s of Paleozoic fossils. 

 (Ann. Mag. Nat. Hist., ser. 4, XIX, 1877, pp. 1H3-8, pi. xix.) 

 The authors characterize very fully the new genua Ascodictyon and describe 

 three species, two from the Hamilton of Ontario and one from the Lower Carboni- 

 ferous of Scotland, and then discuss at some length the systematic pcjsition of the 

 genvis.

 In this small brochure, appearing at irregular intervals, a large number of new 

 species are described, mainly from the Cincinnati group. Some writers have con- 

 sidered that this work should be disregarded on account of its obscure mode of pub- 

 lication. Inasmuch, however, as it has received some recognition, we have deemed 

 it best to recognize the work and regard as valid such of the species as can 1)e iden- 

 tified from the descriptions. The two plates included in the last number are of no 

 value for identifying the species.
