248 Mr. J. Miers on the genus Solandra. 
This species has the colouring of Elaps bivirgatus, Miller, and 
has most probably been mistaken for that species ; but it is of a 
much larger size, and easily known by the large size of the ver- 
tebral scales. 
In the young specimen the spot on the back and sides forms a 
nearly continued stripe, and the outer edge of the ventral shield 
is clouded with black.

SoLaNDRA. 
I nortce this genus, in order to confirm what has been already 
advanced respecting it in the preceding volume of the ‘ Annals,’ 
p- 176, when I endeavoured to show that its relation is decidedly 
with Juanulloa, Marckea and Sarcophysa, constituting with these 
genera a distinct tribe of the Atropacee or Atropinee, and in no 
degree related to Datura, with which it has been classed by all 
botanists heretofore. It will be seen to approach Juanullea in 
its large tubular calyx, which splits generally on one side, in 
consequence of the growth of its large fleshy berry, in the struc- 
ture of which there exists a considerable resemblance in both ge- 
nera, but it differs from that genus, in its much larger and more 
campanular corolla. It bears also great analogy with Brunsfelsia, 
in its large, yellow, fleshy border, with five rounded lobes, greatly 
fimbriated ‘on their margins, and deeply imbricated in eestivation, 
and also in its large berry filled with pulp ; but it differs from this 
last-mentioned genus, in its general habit and in the structure of 
its stamens. It will serve to connect the Solandree with the 
Brunsfelsiee, and in the lmear arrangement shown in the tabular 
view, p. 176, as above quoted, it should have been placed below 
Ectozoma, and immediately preceding Brunsfelsia. I have not 
been able to examine its seeds or to find any analysis of its struc- 
ture, any farther than that the embryo is said to be arcuate; in 
this respect it will probably resemble Juanulloa, Marckea and 
Franciscea, where it is terete, nearly straight or only slightly 
bent, with short, ovate cotyledons. The following is offered as 
an amended generic character :— 
Sotanpra, Swartz. (Char. emend.)—Calyz 5-sepalus, per- 
sistens ; sepala lanceolata, acuta, marginibus in tubum longum, 
cylindraceum, 5-angulatum, mzequaliter et breviter 2-3-par- 
titum, demum hine fissum, valvatim conniventia. Corolla
