184 NATURAL HISTORY BULLETIN. 



from the first edition without correction: 1 "Judging from 

 the figures quoted, this is P androgynum of Poiret; and if so, 

 that name has priority." Having no additional information 

 the author retains P. tetragona. If the change becomes neces- 

 sary the name should be Phegopteris androgyna (Poir), and 

 that of the variety P. androgyna var. megaloda (Schk.). 



The type was quite common in low grounds in the deep 

 woods near Castillo. Some of the pinnae have the veins of 

 contiguous groups free, thus connecting the sub-genera Euphe- 

 gopteris and Gomopteris. 



The variety, P. tetragona var. megaloda (Schk.), was also 

 abundant along the La Juana River and near Castillo. The 

 venation of the Castillo form is represented in Fig. 4, that of 

 the La Juana specimen in Fig. 3. The stipe is purplish-green 

 when fresh. 



Fournier and Hemslev report the type from Granada. The 

 variety has not been reported from Nicaragua. 



5. P. draconopterum {Eaton) Shinick. PI. xix, Figs. 5, 6. 



Aspidium draconopterum Eaton, Fil. Wr. et Fend., p. 2x1.

 Syn. Fil., p. 319. 



Smith 2 refers this to Dryomenis purdiei Smith, but that 

 name, though older, is proposed in the " Botany of the Herald" 3 

 without a description. Hence Eaton's name, which is accom- 

 panied by a full description, is adopted. Smith makes no 

 mention of this species in his "Perns, British and Foreign'''' 

 which was published a year later than the "Historia Filicum" 



Typical specimens were quite common along the high 

 banks of a small stream in deep woods near Castillo. 



The species has not heretofore been reported from Central 

 America, the nearest locality being New Granada, from which 

 Eaton's type-specimens were received.
