Museum I must quite agree with Bell that they have nothing to do with T. Reevesii, 

 but on the other hand I do not find a single character by which to distinguish 

 granulosus with certainty from toreiimaticus. Hell does not point out any cha- 

 racter distinguishing it from toreiimaticus, he only remarks that the suturai fur- 

 rows are not so deep nor so wide as in that species; but this is a feature much 

 too variable to be relied upon for sole specific character. Accordingly I must 

 regard T. granulosus as a synonym of T. toreumaticus. — The specimens of „T. 

 granulosus" mentioned by Bell') from Port Denison, Queensland, are partly Sal- 

 macis Alexandri, partly another Salmacis (probably S. sphwroides, var. pyramidala); 

 only a single small specimen is probably T. toreumaticus. 



In the „Alerf-Echinodermata (p. 119) Bell mentions a specimen of Temnopl. 

 toreumaticus from Port Denison, which „has all the spines which are i)reservcd on 

 it perfectly white, without any bands whatever". I have examined this specimen in 

 the British Museum and can thus assert that it is not T. toreumaticus; its globiferous 

 pedicellariæ have no lateral teeth. To which species and genus it belongs I cannot 

 say, having not examined it sufficiently for that purpose. 



The specimen described by Sladen in his paper on the Asteroidea and Echi- 

 noidea of the Korean Seas") as a young Temnopl. toreumaticus is a Pleurechinus of the 

 species described below as Pleurech. variegatus. (The specimen was examined in 

 the British Museum). Finally the specimen referred by de Meijere to Temnopl. toreu- 

 maticus (Op. cit.) is not that species either. The globiferous pedicellariæ have no 

 lateral teeth, and the spines are yellowish-green with red base; from these two 

 characters it might be supposed to be Salmacis Alexandri''). „Nach anderen 

 Autoren (Döderlein, Bedford) kommen auch Exemplare mit mehr oder weniger 

 geringelten Stacheln vor" says de Meijere (Op. cit. p. 81). AU the specimens I have 

 seen of T. toreumaticus have ringed spines, though sometimes rather indistinctly, 

 when the spines are very dark coloured, and I am not aware that specimens with 

 not-ringed spines have been recorded, except those wrongly referred to toreumaticus 

 by Bell and de Meijere. On the contrary ringed spines do not occur in the other 

 species of Temnopleurus, accordingly the ringed spines form one of the specific 

 characters of toreumaticus, and the assertion thai ringed spines do „also" occur in 

 this species thus sounds rather curious. 



Ives (Op. cit.) regards Temnopl. Hardwickii (Graj') as synonymous with 

 toreumaticus, having found specimens intermediate between these two species as 

 defined by Agassiz. „One specimen having rather deep pits, has the ocular and 

 genital plates covered with prominent tubercles, and other specimens show the

') After the manuscript was finished, de Meijere has kindly lent nic the specimen for examina- 

 tion. It is S. virgulata var. Alexandri or perhaps a new variety. The test is white; no tridentate pedi- 

 cellariæ are found on the specimen.
