110 On the Species of Pseudoboletia. 
The only possible fault then that can, here at any rate, be 
found with me (and I am sure no one will call it a fault) is 
that I put my trust in Mr. Agassiz’s ‘ Revision of the Kehini.’ 
To him therefore what blame is due must be transferred. 
Two questions now remain: the first is, what name shall 
be given to the species which has been till now labelled in 
the British Museum PL. indiana? In the year 1869 that 
eminent zoologist the late Professor Trosehel described in the 
‘ Sitzungsberichte ’ (not ‘ Verhandl.,’ as stated by Mr. Agassiz, 
op. cit. p. 153) two species of Pseudoboletia—P. stenostoma 
and P. maculata: the former appears to be a synonym of 
P. indiana (Mich.) ; the latter is in all probability the species 
which now is found to be without a name, but has been 
labelled P. indiana. 
The “ synonymy ”’ of the species will then stand thus :— 
Pseudoboletia indiana. 
Toxopneustes indianus, Michelin, in Maillard’s ‘ Réunion,’ ed. 2, annex. 
A, p. 5. 
Spheriechinus indianus, Liitken, Bidrag, p. 76 (144). 
Pseudoboletia stenostoma, Troschel, Sitzb. nat. Ver. preuss. Rheinl, 1869, 
p96. 
Pseudoboletia granulata, Agassiz, Rev. Ech. pp. 155 and 455; Bell, 
P, Z. 8. 1881, p. 482.

Pseudoboletia maculata.

p- 96. 
Pseudoboletia indiana, Agassiz, Rev. Ech. p. 456, pl. v. a, figs. 8 and 9; 
Bell, P. Z. S. 1881, p. 483; Agassiz, Chall. Rep. Ech. p. 107. 
The second question that remains for consideration is the 
geographical distribution of the species, in which again there 
is some confusion, owing to the statements made by Mr. Agas- 
siz. In the Rev. Ech. p. 158, the only locality given for 
“P. granulata” is Sandwich Islands, while “P. tndiana” is 
said to come from Masbate, Philippines, Mauritius, Bombay 
and Bourbon. Specimens from the first three of these locali- 
ties are said to be in the British Museum; it is now clear 
that those from the first two are examples of P. maculata. 
For P. indiana Mauritius and the neighbouring islands are 
authentic localities, while, like Tripneustes variegatus, it 
appears too to be found at no less distant a locality than the 
Sandwich Islands. In conclusion it may be added that Mr, 
Agassiz incorrectly ) refixed the sign ® to his “P. indiana”
