REPORT OF THE ECHINOIDEA—-MORTENSEN 135 
Station 5489 (lat. 15°58’ N., long. 119°40’ E.) ; 1,720 meters; May 
9, 1909. One young badly broken specimen. 
Station 5468 (lat. 13°36’ N., long. 123°40’ E.) ; 1,041 meters; June 
18, 1909. Six large badly broken specimens, only one of them nearly 
complete. 
Station 5612 (lat. 0°38’ S., long. 121°44’ E.) ; 1,873 meters; Novem- 
ber 20, 1909. One young badly broken specimen. 
Station 5619 (lat. 0°35’ N., long. 127°15’ E.) ; 796 meters; Novem- 
ber 27, 1909. One young badly broken specimen. 
Station 5654 (lat. 3°42’ S., long. 120°46’ E.) ; 1,473 meters; Decem- 
ber 18,1909. Fragments of two large specimens. 
Station 5668 (lat. 2°28’ S., long. 118°49’ E.) ; 1,649 meters; Decem- 
ber 29,1909. One nearly complete medium-sized specimen. 
Uncertain locality : Fragments of one large specimen. 
Remarks.—It is very regrettable that all these specimens are very 
badly broken; only one specimen, a naked test from station 5468, is 
nearly complete. Evidently the oral side is much more fragile than 
the aboral side; the mud-filled, very heavy intestinal canal causes it to 
break by the capture in the trawl, and in most cases only small frag- 
ments or nothing at all of the oral side is preserved. In the specimen 
from station 5668 the anterior half of the oral side is preserved. To 
some degree it has been possible to glue the fragments together so as to 
get tolerably good aboral sides; the extremely thin fragments of oral 
sides it has in no case been possible to fit together. 
The largest of the specimens is about 108 mm. long, but a good deal 
smaller than Koehler’s largest specimen, which is stated to exceed 130 
mm. in length. The smallest specimen (station 5332) is 50 mm. long. 
Genital pores are fully developed in this young specimen.
