400 THE GORGONIANS OF THE BRAZILIAN COAST. 



with some ellipsoids with a single median whorl of warts; short, close double-heads 

 and double-cones. The tentacle-spicules are bright red, slender, acute, nearly 

 smooth spindles, often as long as the war ted spindles. 



The more slender double-spindles of the type measure 0.14 X 0.04; 0.13 X 

 0.03; 0.12 X 0.04; 0.12 X 0.03; stouter double-spindles, 0.11 X 0.04; 0.10 X 

 0.06; 0.10 X 0.05; 0.09 X 0.05; double-rosettes, 0.08 X 0.05; rosettes, 0.06 X 

 0.05; 0.06X0.06; 0.06X0.04; 0.05X0.04; tentacle spicules, 0.11X0.02; 



0.10 X 0.03 mm. 



The slide was labelled by Professor Kolliker as from the type in the Paris 

 Museum, collected by M. Dupres, 1842. Milne-Edwards gives Brazil as its 

 origin. A branch from a large specimen (No. 892) collected by Prof. James D. 

 Dana, on the Wilkes U. S. Exploring Expedition, in the Bay of Rio de Janeiro, 

 was referred to this species by me in 1869. It was received from the Smith- 

 sonian Institution about 1861. 



The original description is so brief that the identification would be quite 

 conjectural without the spicules of the original type, which were sent to me by 

 Professor Kolliker. It is nearly allied to the preceding species, with which it 

 agrees pretty nearly in color and in the four-rowed arrangement of the calicles. 

 The color, however, is paler and more nearly wine-red, while the calicles are not 

 alf as large and much less prominent. The mode of branching is more distinctlyh 

 pinnate and the branches are more numerous, shorter, and much more slender, 



being less than half as thick. 



Total length of branch, 95 mm.; length of terminal branchlets, 10 to 15 mm.; 

 their diameter, 1 to 1.2 mm.; diameter of calicles, 0.5 mm. and less. 



The more slender larger double-spindles of No. 892 measure 0.12 X 0.05; 

 0.11 X 0.05; 0.10 X 0.04; stouter ones, 0.11 X 0.06; 0.10 X 0.05; double-heads, 

 0.06 X 0.03; rosettes endwise, 0.07 X 0.05; 0.06 X 0.05; 0.05 X 0.05; crosses, 



0.08 X 0.06 mm. . 



The spicules are much like those of L. rubropurpurea, but are smaller, an 

 examination of a large series of specimens might show that they are only oca 

 varieties of one species, though so unlike in size of calicles, etc.
