A large colony from Station 37. 
Characteristic of this species are the following features : 
(1) the lobes are large, tough, and vary greatly in form from robust upstanding cylinders to 
flattened ingrowing lobes, every gradation being represented. Some of the colonies differ 
widely from the others in their growth-form, showing only a few large marginal foldings in 
a manner suggestive of Sarcophytum ; 
(2) the openings of both kinds of zooids are very distinct, even the siphonozooids being visible 
with the naked eye ; 
(3) the autozooids can never be called distant as in L. hedleyi , unless on the margins of the lobes.

The spicules include : 
[a) compact ovals with two median zones and terminal clusters of very compound warts; 
0.2 X 0.08 mm. ; 
( b ) more elongated broad spindles of the same warty type, 0.24X0.1 mm.; 
(z) slender spindles with as many as four zones of compound warts; and similar forms without 
zoning; 0.26 X 0.03 mm. ; 
( d ) slender spindles with conical prominences not compound; some of these are very minute, 
and obviously young forms, 0.15x0.03mm.; 
(z) interesting almost smooth, short, broad, truncate forms with only incipient prominences in 
two zones; these are connected with the ( a ) type by transition forms, and are evidently half- 
finished spicules, 0.15x0.05mm.; 
(/) a few forms broader at one end and approximating to “clubs”; 0.15x0.02mm.; 
(jr) a few crosses, average greatest diameter 0.1 mm. 
It should be noted that different specimens vary greatly in the proportions of narrow 
spindles and compact ovals. 
The large brown convoluted colony from Station 37 has a maximum height of 10 cm.; 
the irregular disc is about 23 cm. in length, by about 9 cm. in breadth. 
A specimen from Station 213, Saleyer, has a curious flattened trunk region tapering off 
ventrally to a sharp edge and with no base of attachment. A similar type of sterile trunk 
like an inverted cone was seen in one of the specimens of Similaria jlexibilis (O. G.). The 
specimen probably, we imagine, grew upright in a sandy bed. From the sterile trunk arise long 
and rather twisted lobes most of which branch into smaller lobes. Maximum diameters of the 
trunk are 5.8 cm. X 9 mm.; height of trunk 3 cm.; total height 6.2 cm.; longest undivided lobe 
2.2 cm. X 6 mm. The lobes are flexible but brittle, and the whole surface is rather orranular.
