After a short historical account of the genus Ceratolejeunea its more 

 important peculiarities are considered with special reference to related 

 genera. The genus as a whole is unusually well defined^ but some of 

 the species are so variable that it is difficult to distinguish between them. 

 Apparently the most trustworthy characters are those derived from the 

 leaf-cells, the lobules and the perianths. At the present time the follo- 

 wing seven species are known from Puerto Rico: Ceratolejeunea 

 spinosa (Gottsche) Steph., C. valida Evans sp., nov., C. brevinervis 

 (Spruce) Evans, comb, nov., C. Schwaneckei^it^h.., C.variabilis {L'xnAtnh.) 

 Schiffn., C Sintenisii Steph. ^ and C. patentissinia (Hampe and Gottsche) 

 Evans, comb. nov. Two other species C. ceratantha and C. cornnta, 

 have also been accredited to the Island, but the evidence that they grow 

 there is not wholly conclusive. C. spinosa, C. valida, C. Schwaneckei 

 and C. patentissima are figured on the two plates. A. W. Evans.

Lophozia excisa (Dicks.) Dumort. is here first reported from New 

 England, the record being based on a specimen from New Hamp- 

 shire. L. Muelleri (Nees) Dumort is likewise new to New England, 

 the specimen Coming from Connecticut. Several localities are cited 

 for L. porphyroleuca (Nees) Schiffn., a species ascribed to New Eng- 

 land by Austin and latterly shown to be distinct from L. ventricosa. 

 Lophocolea heterophylla (Schrad.) Dumort is shown to be exceedingly 

 variable and is believed to include L. Austini Lindb. and L. Macounii 

 Austin. Scapania Oakesii Austin is piaced by the writer, following 

 Müller, as a synonym of 5. dentata Dumort. 5". gracilis (Lindb.) 

 Kaalaass is reported from Maine. Ptilidium pulcherrimum (Web.) Hampe
