REPORT ON THE ECHINOIDEA—MORTENSEN 335) 
The color of the preserved specimens is a uniform dirty-gray mud- 
color, but it seems evident that this is due to the poor preservation. 
Localities —Station 5241; in the vicinity of Pujada Bay; Uanivan 
Island (N.) bearing S. 68° E., 3 miles distant (lat. 6°50’45’’ N., long. 
126°14’38’’ E.); 393 meters; soft gray mud; May 14, 1908. Two 
young specimens. 
Station 5242; in the vicinity of Pujada Bay; Uanivan Island (N.) 
bearing S. 56° E., 4 miles distant (lat. 6°51’53’” N., long. 126°14’10’ 
KE.) ; 8349 meters; bottom temperature 17.83° C.; soft gray mud; May 
14, 1908. Five specimens. 
Station 5248; in the vicinity of Pujada Bay; Uanivan Island (N.) 
bearing S. 66° E., 3.1 miles distant (lat. 6°50’55’’ N., long. 126°14’35”” 
E.) ; 898 meters; bottom temperature 17.56° C.; gray mud; May 15, 
1908. Four specimens. 
Station 5244; in the vicinity of Pujada Bay; Uanivan Island (N.) 
bearing S. 52°30’ E., 4 miles distant (lat. 6°52’05’’ N., long. 126°14’15”’ 
E.) ; 313 meters; gray mud; May 15, 1908. Four specimens. 
Remarks.—All these specimens are in a rather poor state of pres- 
ervation; the two young specimens from station 5241 are in very 
poor condition. 
A more detailed description, accompanied by the necessary illustra- 
tions, will be given in the Monograph of the Echinoidea, vol. 3, pt. 1. 
It is interesting to find this new species at the same localities, off 
Uanivan Island, where also the above mentioned peculiar form of 
Micropyga tuberculata was found. But whereas the latter was 
scarcely sufficiently characterized for being regarded as more than 
a local race, the Hvemopyga specimens are so well characterized that 
they must decidedly rank as a distinct species.
