REPORT ON THE HOLOTHURIOIDEA. 
241 
LIST OF LOCALITIES AT WHICH SPECIMENS TOO FPAGMENTARY FOR 
ACCURATE DIAGNOSIS WERE OBTAINED. 
Statiox 274. — September 11, 1875 ; lat. 7° 25' S., long. 152° 15' W. ; depth, 2750 
fathoms ; bottom temperature, 35° T ; Radiolarian ooze. A single pedate Holothurian, in 
such a defective state that no examination is possible. The specimen probably belongs 
either to the Psychropotidse or to those forms of deep-water Aspidochirotae wdiich present 
vhemselves under a shape like that of some of the Psychropotidse. 
Station 244. — June 28, 1875 ; lat. 35° 22' N., long. 169° 53' E. ; depth, 2900 
fathoms; bottom temperature, 3 5° ’3; red clay. One very fragmentary specimen. The 
almost cylindrical ambulacral appendages, probably pedicels, are minute, numerous, and 
especially crowded along the sides of the body ; they do not present any arrangement in 
rows. The ventral surface seems to be devoid of pedicels. The deposits of the body- wall 
consist of numerous crowded tables, the delicate disks of which attain a considerable 
size, about 0‘2 mm. in diameter, and are pierced by six large holes surrounding a small 
central hole ; the holes are often not closed, so that the disk seems to consist of six 
rods radiating from the perforated centre. The spire is composed of three rather 
long rods and a transverse beam situated near the disk. The spire terminates in three 
very long teeth. The pedicels are supported by a few more or less curved, spinous rods ; 
their terminal plates are absent, having possibly been dissolved by some impurity in the 
alcohol. The deposits are very like those in Holothuria lactea, but the species differs 
from the latter by possessing far more numerous pedicels, in having the supporting rods 
of the pedicels very spinous, &c. There is good reason for believing that the two forms 
in question may be referred to the same genus, but the material is inadequate to decide 
this point. 
Station 325.— March 2, 1876; lat. 36° 44' S., long. 46° 16' W. ; depth, 2650 
fathoms; bottom temperature, 32° 7 ; blue mud. Some very fragmentary specimens, 
possibly allied to the Elasipoda. 
Station 160.— March 13, 1874; lat. 42° 42' S., long. 134° 10' E. ; depth, 2600 
fathoms; bottom temperature, 33° ’9 ; red clay. A fragmentary Holothurid with 
respiratory- trees, but possibly without ambulacral appendages. Body of a narrow 
cylindrical form. Colour white. Two Polian vesicles ; and apparently two bundles of 
slender, slightly branched genital tubes, one on each side of the dorsal mesentery. 
Station 241.— June 23, 1875 ; lat. 35° 41' N., long. 157° 42' E. ; depth, 2300 
fathoms ; bottom temperature, 35°'l ; red clay. Two very macerated specimens with 
the deposits dissolved. 
Station 271. — September 6, 1875; lat. 0° 33' S., long. 151°34'W.; depth, 2425 fathoms; 
bottom temperature, 35°; Globigerina' ooze. Fragments of one specimen (PI. X. fig. 10).
