140 PSYCHROPOTIDAE. 
Euphronides verrucosa. 
Plate 1, fig. 2. 
Lupwie, 1893. Bull. M. C. Z. 24, p. 107. 
The representative, from station 4742, of this fine species is in fairly good 
condition and is a very large one, nearly 200 mm. long by 50 mm. wide. The 
colors in life are shown on Plate 1, but in the preserved specimen, the lower sur- 
face is very dark purple while the upper side is light, dull rose-purple. There 
are only sixteen tentacles. The characteristic calcareous spicules of the dor- 
sal side are very conspicuous. 
The specimen from station 17 is labeled by Mitsukuri “Euphronides bifur- 
cata K. & V.” and is accompanied by the following note :— 
“Specimen very much contracted and distorted. 16 tentacles. A little behind the posterior, and 
one-third of the total length on the dorsal surface, 1 pair of not very long nor very large appendages, 
1.lcm.long. 2 more pairs of much smaller appendages in front. At the dorso-ventral border, irregular 
lobed brim. Body not very flat. Posterior part dorsal high. Ventral surface sole-like, flat. A row 
of paired pedicels on the median ventral ambulacrum. On the dorsal, a number of warts, each sup- 
ported by one four-branched spicule, from which the central needle projects.” 
I have examined the specimen with great care but fail to find any dorsal 
appendages nor can I distinguish the specimen in any adequate way from that 
from station 4742 which I have referred to verrucosa. Whether Mitsukuri 
made a mistake, or whether the mistake is mine, or whether bifurcata K. & V. 
is identical with verrucosa Ludwig, more material alone can determine.

The two representatives of this species are very big adults and are much 
the largest deep-water holothurians in the collection. The specimen from 
4658 is in remarkably perfect condition; the body is 170 mm. long, with the 
tail 110 mm. in addition; the maximum width for the body, as well as for the 
tail, which has convex lateral margins, is 45 mm. The tail is very flat and 
distinctly notched at tip. The general color is gray above becoming purple 
below, with the lower surface of the tail reddish ; tentacles purple. The 
specimen from 4721 (Plate 1, fig. 1) is not in as fine condition but is still
