Taxonomic notes
Xia (1985: 71) agrees with Yamamoto (Guam workshop) that what they identified as G. blodgettii should be compared with type or topotype material in order to be certain of the identification. Yamamoto (1985: 77) notes that "G. blodgettii" and G. cylindrica appear to be closely related. Chiang (1985: 81) agrees with Xia and Yamamoto that the Chinese, Japanese and Taiwanese specimens they each identified as G. blodgettii are the same entity, but that the question as to their identity with Caribbean and type specimens is still to be resolved.

General environment
This is a marine species.
