Gonimaretia tylota H. L. CLarkK, Hawaiian and other Pacific Echini, Echinonei- 
dae... Spatangidae, p. 241, 1917; Catalogue of the Recent sea-urchins in 
the British Museum, p. 226, 1925. 
Locality.—Station 5467, San Bernardino Strait (lat. 12°56’ N., long. 
124°25’ EK.) ; 494 meters; June 24, 1909. Three specimens, more or 
less broken. 
Remarks.—The best-preserved specimen is 43 mm. long, therefore 
the largest on record; it is 85 mm. broad and 20 mm. high. Another 
specimen evidently was somewhat larger, but it is too fragmentary and 
incomplete to be measured. 
The genus Gonimaretia, established by H. L. Clark (op. cit. 1917), 
with the species ¢ylota as the genotype, is in my opinion not distinguish- 
able from Pseudomaretia. It is not the place here for a discussion of 
this matter; it will be dealt with in my Monograph of the Echinoidea, 
volume 5, under the genus Psewdomaretia.
