400 . THE VOYAGE OF H.M.S. CHALLENGER. 
There is an example of this species in the collection made during the “ Porcupine” 
Expedition, but no record of the locality or depth is given. It is perhaps the starfish 
referred to by Sir Wyville Thomson! as “a fine Scytaster, probably identical with the 
Asterias canariensis of d’Orbigny.” This erroneous view of the identity of the Asterias 
longipes of Retzius with the Asterias canariensis of @Orbigny had been previously sug- 
gested by Liitken,* and the form was ranked by him as a Scytaster. There is no other 
example belonging to this family in the ‘‘ Porcupine” collection, recerved by me. 
The starfish which bears Gray’s name of Astropecten longipes in the British Museum 
is a Chxtaster longipes; and there appears to be little doubt that this is the form named 
by Gray, notwithstanding the contradictory character of some of the statements in his 
short diagnosis of the species.

This genus was removed from the Linckiide by Viguier, and placed in his family 
Goniasteridz ; I prefer, however, to revert to Perrier’s classification of the form amongst 
the Linckiide. The genus is essentially an inhabitant of the tropics, and the type species 
may be regarded as a common form. 
Chorology of the Genus Fromia. 
a. Geographical distribution:— 
Iyp1an Ocean: Three species between the parallels of 30° N. and 30° S. 
Fromia milleporella, from the Red Sea, Mauritius, Madagascar, 
Ceylon, and extending into the Eastern Archipelago and Pacific. 
Fromia tumida, from Ceylon. Fromia indica, exact locality 
unknown ; recorded as “ mers de l’Inde.” 
Eastern ARCHIPELAGO: Two species between the parallels of 10° N. and 10° 8. 
Fromia milleporella, from the Moluccas and Amboina (fide de 
Loriol), extends into the Indian Ocean and also into the Pacific. 
Fromia monilis, from Amboina.
