18 Journal of Entomology and Zoology 
scribed by Déderlein from Tokyo Bay. My opinion (previously 
published) that caryi and japonicus are synonyms is thus strongly 
confirmed. 
“Tt is the largest ophiuran, by far, hitherto recorded. Its disc 
is about 130 mm. across. The largest specimen I have seen hitherto 
is 115 mm. Déderlein, in his monograph, has 110 mm. as his maxi- 
mum measurement.”
