few simple low conical prominences, sometimes in zones, sometimes irregularly scattered. We 
have not seen these in any other species of Sarcophytum known to us or figured. The following 
measurements were taken : 0.48 mm. X 0.02 mm.; 0.42 mm. X 0.04 mm.; 0.25 mm. X 0.02 mm. 
There are numerous more ordinary tapering spindles, with warts simple, or compound, 
zoned (often very markedly), or irregular. Almost all these spindles are relatively narrow. The 
following measurements were taken: 0.25x0.04mm. 
Numerous pseudo-clubs occur, some of them rather coarser than the spindles, from which 
they are derivable. 
A few elegant crosses were seen. 
The spicules of the stalk are mainly robust spindles, relatively broader than those in the 
capitulum, with simple or compound warts, usually zoned. The following measurements were 
taken : 0.32 mm. X 0.07 mm.; 0.22 mm. X 0.07 mm.; 0.08 mm, X 0.02 mm.

To this species we refer several colonies with the following characteristics : 
[ci] there are numerous digitiform, elongated, terminally rounded lobes; 
(b) the autozooids are relatively few and distant; the siphonozooids are crowded and very distinct; 
(1 c ) the spicules are of two types in varying proportions. (1) The great majority are substantial 
spindles, with zones of very compound warts, some elongated, others more compact. Yet the 
latter rarely approach the compact ovoids so characteristic of L. crassum. (2) There is a 
minority of rather smooth spindles with simple conical prominences. 
Some of the younger, smaller colonies have the lobes considerably less developed in 
length, but all stages of growth are shown. 
Luttschwager (Revision der Familie Alcyoniidae, 1915, p. 33) has incorporated this species 
with L. paucijlorum (Ehrb.), but we feel that the typical markedly elongated, digitiform lobes, 
the more distant autozooids, and the narrow elongated spindles found in L. candelabrum justify 
us in retaining the latter as a separate species.
