Localities —Station 5348, Palawan Passage (lat. 10°58’ N., long. 
118°38’ E.) ; 686 meters; December 27, 1908. One large specimen. 
Station 5646, Buton Strait (lat. 5°31’ N., long. 122°23’ EK.) ; 834 
meters; December 16, 1909. ‘Three large specimens. 
Station 5656, Gulf of Boni (lat. 3°18’ S., long. 120°37’ E.) ; 886 
meters; December 19, 1909. ‘Two medium-sized specimens. 
Station 5657, Gulf of Boni (lat. 3°20’ S., long. 120°36’ E.) ; 900 
meters; December 19, 1909. ‘Three medium-sized specimens, all very 
badly broken. 
Station 5658, Gulf of Boni (lat. 3°33’ S., long. 120°31’ E.) ; 933 
meters; December 19, 1909. Fragments of an old test. 
Remarks.—These specimens conform perfectly with the description 
given by Koehler, op. cit., 1914; but whereas the largest of the /nvesti- 
gator specimens was 76 mm. long and the largest of the Siboga ones 
86 mm. long, the largest of the specimens from station 5646 is 96 mm. 
long, the largest known till now. This specimen was denuded and 
has afforded a very fine preparation of the test; it will be figured in 
volume 5 of my Monograph of the Echinoidea.

Lovenia triforis KoEHLER, Echinoderma of the Indian Museum, Echinoidea, pt. 
1, Spatangidés, p. 124, pl. 12, figs. 9-13, 1914. 
Locality.—Station 5355, North Balabac Strait, north of Borneo 
(lat. 8°08’ N., long. 117°19’ E.); 81 meters; January 5, 1908. One 
specimen. 
Remarks.—This species was hitherto known only from the single 
incomplete specimen taken by the /nvestigator in the Gulf of Mar- 
taban. Later (1914) I took one specimen near the Goto Islands, Japan, 
and (1929) a few specimens in the Bali Sea, all except one very badly 
broken. The specimen from the A/batross is in fairly good condition, 
the test not broken; it is 33 mm. long. 
The rostrate pedicellariae, the only type of pedicellariae found on 
this specimen, differ from those of the specimens from the Bali Sea 
in being smooth, whereas they are more or less conspicuously knobbed 
in the Bali Sea specimens. Since, however, there are no other differ- 
ences, and all other characters are identical, and, moreover, only quite 
small examples of these rostrate pedicellariae are found, I can have 
no doubt that this specimen from off North Borneo is conspecific with
