Herdman (1886, p. 287 and following) identifies doubtfully with 
L. alhiditm Verrill specimens collected by the Challenger Expedition 
off San Jago, Cape Verde Islands, in 100 to 125 fathoms and 10 to 20 
fathoms, and from Simons Bay, Cape of Good Hope, 10 to 20 fathoms. 
Another specimen, from Tangier Bay, Morocco, he doubtfully identi- 
fies with L. albidum var. luteohim Verrill. Herdman based these, 
determinations upon a comparison of the Challenger specimens with 
examples of Leptoclinum albidum and L. albidum var. lufeohim received 
from the United States Fish Commission, which sent out sets of labeled 
specimens of the common New England invertebrates to various foreign 
museums. But the specimens that were sent out labeled L. albidum 
ov L. albidum var. luteolum were, since they came from Vineyard 
Sound (Verrill and Rathbun, 1879, p. 231; ISIcDonald, 1889, p. 858), 
really D. [L.] lutarium. Hence, it is to this species, not to albidum, 
that the Challenger specimens are allied. Indeed, Herdman's de- 
scription and figures would show this, even if the records were wanting. 
The Tangier Bay specimen (which he figures, PI. 11, fig. 10-15) 
may be left out of account here, as Herdman says its zooids have but 
three rows of stigmata. In regard to the others, since Herdman after 
a direct comparison was doubtful as to their identity, it will be better to 
reserve decision until more material shall have been collected from 
those regions, and to follow a like course in regard to a large colony 
collected at the Philippine Islands, which had long-rayed, regularly 
stellate, sharp-pointed spicules. This colony he describes and figures 
(PI. 25, fig. 11-14) as a new variety {grande) of L. albidum. 
Sluiter (1905, p. 103) identifies a specimen of this genus from the 
Bay of Jibuti, East Africa, with L. albidum var. luteolum Verrill, 
apparently largely on account of its orange red color. 
Genus Leptoclixides Bjerkan, 1905. 
Resembles Didemnum [Leptoclinum] in most characters. Four 
rows of stigmata. Spicules present in the test. Atrial orifice situated 
far back on the thorax and produced into a funnel-like, more or less 
posteriorly directed tube, without a languet. 
Leptoclinides faeroensis Bjerkan.
