those from the Bali Sea. The species Z. triforis is thus now known to 
be distributed from the Bay of Bengal to Japan, and must be sup- 
posed to have its center of distribution in the Malay region. 
LOVENIA DODERLEINI Mortensen ACUMINATA, new variety 
Localities—Station 5161, Tinakta Island, Tawi Tawi Group (lat. 
5°10’ N., long. 119°53’ E.); 29 meters; February 21, 1908. One 
specimen. 
Station 5164, Tawi Tawi Group (lat. 5°02’ N., long. 119°52’ E.) ; 
33 meters; February 24, 1908. One specimen. 
Type.—vU.S.N.M. No. E.7160, from station 5161. 
Description—The type specimen is well preserved, 32 mm. long, 
26 mm. broad, and 14 mm. high. The other specimen is smaller, 25 
mm. long, also well preserved. 
This form differs from typical Z. déderleini, which will be described 
in volume 5 of my Monograph of the Echinoidea, in being markedly 
attenuated posteriorly (particularly the large specimen). Further, 
it differs in having the internal fasciole single anteriorly (double 
in the typical déderleinz), and in having the stalk of the globiferous 
pedicellariae thin, not at all thickened as it is in the typical déderleini; 
these pedicellariae are found only in the type. That ophicephalous 
pedicellariae are wanting is probably not a constant character, since 
they are not always present in typical déderleini. In all the other 
characters these specimens agree with typical déderleini (apart from 
the fact that the aboral globiferous pedicellariae so characteristic 
of that species are not found). 
It is quite probable that these specimens actually represent a dis- 
tinct new species; but with the quite insufficient material at hand I 
do not think it advisable to establish it as more than a variety of 
L. doderleini, with which it is at any rate very closely allied. 
Genus BREYNIA Desor 
BREYNIA ELEGANS Mortensen 
Locality — Station 5152, near the Tawi-Tawi Islands (lat. 5° 23’ N., 
long. 120°16’ E.) ; 62 meters; February 18, 1908. 
One specimen, a very badly broken, incomplete test. The frag- 
ments could be fitted together so as to form a tolerable specimen, 
95 mm. long, 73 mm. broad, and 36 mm. high. 
Remarks.—Vhough in poor condition, this specimen can be identi- 
fied with certainty as belonging to the new species B. elegans, 
established for a large specimen from the Kei Islands, also rather 
badly broken, but still in much better condition than the specimen 
from the Albatross, particularly in that the spines are preserved. It 
was thus necessary to take the specimen from the Kei Islands as the
