Dendeicopoea Haedyi, JF. B. Clarke. 
PI. VIII, Pig. 1.^ 
The coBnoecmni of this species is in the form of a fan, a little longer 
than broad. The axis, or principal branch, which is straight, tapers from the 
base to the apex ; both sides of this axis carry two principal lateral or acces- 
sory branches ; upon one of the sides these principal lateral branches are 
situated at a short distance from the base, and are inserted at an .ansrle of 
o 
about 35° ; on the other side they spring from near the middle of the length 
of the axis, at a short distance from each other, the angle of insertion of 
the upper branch being 35°, while the angle of the lower branch is a little 
more acute. These four branches all taper from their insertion towards their 
extremities. The smaller branches, to which all these give rise, are inserted 
at a very acute angle ; they are placed at equal distances from each other, 
are filiform, and nearly parallel ; they are united by cross-bars, giving rise 
to sub-rectangular fenestrules, generally much longer than broad. The 
external surface is ornamented with a trijole row of cells arranged quin- 
cuncially, and closely pached together; it is not keeled; there are ten or 
eleven small cells on the margins of the fenestrules. 
Dimensions. — The length of the largest specimen of this species known 
to me, but which is very incomplete, is about five and a half centimetres, the 
breadth four centimetres, and the diameter of the axis does not reach a milli- 
metre at the base. 
Formation and Localities. — This species, which has no known analogy, 
was found with the preceding, associated with Sjpirifer glaher, Martin.
