114. R.obesa West & G.S.West, n. sp. (Tab. nostr. IV, fig. 53—54.) 
Cellule mediocres, solitarize vel bine (interdum 3), libere na- 
tantes, oblique ellipsoidese, paullo curvate, margine exterior! con- 
vexo vel recto et levissime retuso, margine interiori valde convexo, 
apicibus spina robusta curvata brevi acutissima preeditis. 
Long. sine spin. 29—30,5 #, eum spin. 42—46 ; lat. 14; long. 
spin. 6,5—7,5 p. 
One cell possessed a short, thick, extra spine near to one pole. 
This plant differs from the other species of Reinschiella in the fact 
that the ventral (or internal) margin is much more convex than the dorsal 
(or external) margin. The spines thus appear to be curved in the op- 
posite’ direction to the apparent curvature of the cells. 
Among various Palmellacee in stagnant water in the jungle.
