Newly collected specimens of the Atlantic
Myxaster sol and a further record of
Pythonaster atlantidis add to the known occurrence records and the morphological variation of these rarely encountered species. Distribution data suggests that both
M. sol and
P. atlantidis are pan-Atlantic species and are similar to other widely distributed deep-sea asteroid species. Re-examination of the type of
Myxaster perrieri further supports its placement within
Myxaster and not Pythonaster as has been recently reported.
