Scandinavia, Brita, and the United States. Pentagonaster pla- 
centa, in the Mediterranean and Adriatic. Pentagonaster mirabilis, 
in the Gulf of Smyrna (I am in great doubt as to the distinctness 
of this form from Pentagonaster placenta). *Pentagonaster sem- 
lunatus, off the coast of Senegal and off the Cape Verde Islands, 
passing thence to Brazil, and extending northward to South Caro- 
lina. It is also recorded from Zanzibar, Celebes, and China. Pen- 
tagonaster crassus, Pentagonaster deplasi, Pentagonaster gosselin, 
and Pentagonaster perriert (= Pentagonaster grandis, Perrier),' off 
the coast of Morocco. Pentagonaster gosselini is also found off 
the Canaries and off the Azores, and Pentagonaster perriert off the 
Azores. *Pentagonaster lepidus, Pentagonaster fallax, and Penta- 
gonaster (2) elongatus, off the Azores, Pentagonaster vincenti, off the 
Canaries, and Pentagonaster hesitans, off Cape Ghir. The following 
series of species are all from the West Indian area and Gulf of Mexico: 
Pentagonaster parvus, Pentagonaster grenadensis, Pentagonaster 
dentatus, Pentagonaster affinis, Pentagonaster (?) alexandri, and 
Pentagonaster intermedius. (I am doubtful as to the accuracy of refer- 
ring Perrier’s three species, Pentagonaster alewandri, Pentagonaster 
elongatus, and Pentagonaster intermedius to Pentagonaster as now de- 
fined. It seems to me not improbable that the first will prove to belong 
to the genus Nymphaster, and the second perhaps to Paragonaster.) 
* Pentagonaster patagonicus, off the eastern coast of South America, near 
the Atlantic entrance to the Strait of Magellan ; and it is also found 
on the Pacific side of the Strait near the entrance to Smyth Channel. 
Paciric: Nine species between the parallels of 40° N. and 55° S. 
Pentagonaster semilunatus, off the coast of China, being also found 
in the Atlantic off the coasts of Brazil, South Carolina, and Senegal. 
*Pentagonaster japonicus and * Pentagonaster arcuatus, off the coast 
of Japan. Pentagonaster (2) fonki, off the coast of Chili. Penta- 
gonaster (?) belli and *Pentagonaster patagonicus, in the Strait of 
1 Professor Perrier has described (Ann. Sct. Nat. (Zool.), 1885, t. xix., Art. No. 8, p. 35), under the name 
of Pentagonaster grandis, a new species represented by a large series of specimens dredged during the “ Talisman” 
Expedition off the coasts of Morocco, the Sahara, and the Azores. Unfortunately the name “ grandis” is already 
appropriated to another species of Pentagonaster, from Western Australia, described by Gray in 1847, under the 
name of Tosia grandis (Proc. Zool. Soc. Lond., 1847, p. 80; Synop. Spec. Starf. Brit. Mus. 1866, p. 11, pl. 3, 
fig. 1). The type of Gray’s species is in the British Museum. As Perrier’s form appears from the short de- 
scription given to be clearly distinct, and as the locality and conditions of existence would lead to the same 
inference, it seems to me necessary that the name should be changed to avoid confusion. I have therefore 
substituted that of Pentagonaster perriert for the West African species, under the conviction that the form can 
bear no more appropriate name than that of its able describer.
