Localities —Station 5582 (lat. 4°20’ N., long. 118°58’ E.); 1,480 
meters; September 26, 1909. One specimen. 
Station 5618 (lat. 0°37’ N., long. 127°15’ E.) ; 763 meters; Novem- 
ber 27, 1909. One specimen. 
Station 5648 (lat. 5°35’ S., long. 122°20’ KE.) ; 1,023 meters; Decem- 
ber 16,1909. One specimen. 
Remarks.—All these specimens are badly broken, but it has been 
possible to glue the fragments together so as to give a fair idea of their 
shape and size. The largest, the one from station 5582, is 92 mm. 
long, about 50 mm. high, and 80 mm. broad; the two others are a little 
smaller, about 80 mm. long. 
They agree very closely with the illustrations given in the Chal- 
lenger Wchini, plate 25; particularly the spine-covering is quite as 
shown there, the spines being short and fairly robust. In a specimen 
at hand from Japan, a cotype, the spines are somewhat slenderer ; 
but I think it beyond doubt that these specimens are identical with the 
typical form from the Japanese seas. It is not quite clear whether 
the specimen(s) taken in the Philippine seas by the Challenger (sta- 
tion 210) are actually Z. murray? (the fragments of a large specimen 
mentioned by A. Agassiz, p. 168, are rather certainly Z. spectabilis) ; 
but the specimens collected by the Albatross prove that ZL. murrayi 
occurs in the Philippine seas.
