This species is said to have come from Mexico, but probably came originally 

 from some point in the East Indies. Ijnnanis places it in the synonymy of 

 his Asterias pectiimta. 



LUNA MARINA ALTERA.

No habitat is given for this form, which appears to be one of the Comas- 

 teridse. Linnsus refers it to his Asterias pertivata.

This species is founded upon an inadequate description coupled with an

" My friend Mr. Covert, on a voyage from Canton to New York, during 

 1821, cast anchor with eighteen fathoms of line (one hundred and eight feet) in
