WALTERIA LEUCKARTI Ij. 



Pis. XII & XIII. 



Walte^'ia leuckarti, Ijima '96 p. 251. 

 Hyalodendron navalium, Moore '98. 



The exquisitely tree-like Euplectellid from Japan recently 

 described and figured by J. P. Moore under the designation of 

 Hyalodendron navalium n. gen., n. sp., is indubitably identical 

 with my Walteria leucharti previously described in the * Zoolo- 

 gischer Anzeiger.' The brevity of my description may have had 

 much to do in causing Moore's failure to recognize the identity. 

 The creation of a new genus to receive the species is, in my 

 opinion, inadmissible. The description given by Moore is on the 

 whole good, but requires some important additions and correc- 

 tions. 



Numerous specimens have passed through my hands. The 

 exact localities in the Sagami Sea, where specimens of the species 

 have been obtained by Kuma, are as follows : 



Outside Okinose, 717 m. (500 /m'o = 392 fms.). 



Near Mochiyaraa, 1000 m. (700 /wVo=ô46 fms.). 



Homba, 500-572 m. and over (274-313 fms. +). 



Gokeba, 572 m. (400 /wVo = 313 fms.). 

 Fragments and grains of tufa attached to the basal disc 

 attest the nature of the bottom. 



Once at Gokeba, a haul of the long-lines brought up large 

 fragments of four different individuals at a time. From Outside
