 up to 20 cm. Calcareous ring, as Selenka's fig. 7.j. C'uviorian

RemnrU : — As the above list of the specimens examiiR'<l by 

 myself shows, tlie I'ange of this species in eastern Asiatic waters 

 extends from the Philippines througli Formosa (Hattan I.) and 

 tlie Liu-Kin group to Satsuma from which ])rovince I have 

 specimens from several localities. Then coming up along the 

 Pacific side of Japan proper, there are specimens from Ilyuga, 

 Tosa, and finally quite uji north from the Haehijo and Kozu Is. 

 in the Shiehito gi'oup of Izn. The last named island lies at about 

 34' 20' X. Lat., and is over 8' north of the most northern locality 

 hitherto reported. Although Kozu L is almost within sight of 

 Misaki. the species has not been obtained at the last locality. 

 This is prol)ably due to the fact that both Hachijo and Ko^u are 

 almost in the direct lino of the main current of the wanu Kuro-.Shiwo. 



Ambulacral appendages are found all over the body, hi all 

 eases in Avhich I have been able to make sure, there is a clear 

 demai-eation betwc^en the ventral and the dorsal surfaces. The 

 pedicels on the ventrum ai'o much more numerous than those on 

 tho dorsum. Tiiey lack supporting rods. Thkel places this 

 species among those whose ventral pedicels are not arranged in 

 longitudinal series. Although this seems to be the case with 

 large and old specimens, it is diirerent with young individuals. 

 In these three longitudinal rows of pedicels are distinctly recogniz- 

 able. In a specinwn 4."> cm. long from Formosa, the median 

 series possesses four rows of pedicels while the two lateral series 

 consist of two I'ows each. In another IJ) cm. Ioult. this ai-i'ani:e-
