beria minasica attention may be called to the coincident corres- 
pondence of the truncate ends of the lobes, which often retain 
minute laceration fragments at the corners, to the width of the 
seed bases, and the line of separation of the latter ; and the textural 
similarity betwen the lobe end and the chalazal region of the 
fruit (1). The discovery of material that will conclusively deter- 
mine this question is much to bedesired. As already stated in my 
remarks concerning the genus Arberia Iam more inclined to regard 
it as the inflorescence of Gangamopteris than of Noeggerathiopsis 
though the Cardiocarpon (Samaropsis) Seixasi by their close relations 
to the Northern Cardiocarpa argue very strongly for a Cordaitean 
relationship, and consequently, with Noeggerathiopsis. 
Arberia minasica is distinguished from Arberia indica (2) the 
only other species of the genus, from the Talchir-Karharhari series 
by its small size, more oval form and especially by its very deep 
dichotomous dissection in slender lobes that taper but little. 
Locality: Northeast of Minas, Santa Catharina. Horizon about 
55 meters above the granite or 225 meters below the Iraty black 
shale. Lots 3586 and 3921. 
Derbyella nl. g. 
Under the above name I shall describe a type of fertile scaleleaf 
consisting of a small, oval or oblong fleshy lamina, slightly con- 
stricted at the base to a broad attachment and bordered by narrow, 
radiating, close, oblong scales. The nervation is dichotomous from a 
number of parallel primary nerves entering at the base of the leaf. 
A single nerville passes to the base af each of the small marginal 
lobes; the latter are more or less distinct, dorsaly convex, ventrally 
concave, usually somewhat twisted, and in most cases turned slightly 
upward toward the apex of the scale. At the base of the scale is 
situated alargesporangium (?) which in the typ especies, Derbyella 
aurita, nearly equals in diameter the width of the lobe. A short 
branchlet of the lobe nerve passes from the distal (ventral) side of the 
latter to the sporangium (?). The characters of the type so strongly 
resemble those of some of the fertile leaves among the living cycads 
that they seem to demand assignment to the Cycadofilices.
