156 SVEN LOVEN, ON THE ECIIINOIDEA DESCRIBEU BY LINN.BUS. 



The Jndian Ocean is given as the habitat of this species, 

 no doubt by a mistake consequent on the interchange of de- 

 scriptions. Thirteon out of the fourteen species forming the 

 original set of Ecliinoids in the Queen's cabinet were from 

 the seas of the Old World, mostly from the East Indies. Of 

 låter additions tw^o are the commonest of West Indian species, 

 and one of them is the Echinas Lucunter L. It may be taken 

 for granted that these were in the collection presented to the 

 Queen in 1 754 by Colonel C. G. Dahlberg, which contained 

 ;^some things from the West Indies»^), and that Linnjbus de- 

 scribed them when at Drottningholm dnring the last days of 

 September in that year. 



In tlie S. N. ed. 10 reference is made to one figure only, 

 that given by Gualtieri, t. 107, f. C, which is too rude to be 

 admitted. The M. L. U. adds Seba, III, t. 11, f. 11, which 

 seems acceptable. Lastly the S. N. ed. 12 subjoins Klein, 

 ed. gäll., t. 2 f. C. This was intended for a repetition of 

 Klein, ed. german., t. IV f. A, which together with f. B to- 

 lerably well represents a middle-sized specimen of Colobo- 

 centrus atratus L. But the French engraver had neglected 

 reversing his original, and thus disguised it. — To his f. C, 

 D on t. III, which are passable figures of the E. lucunter L., 

 Klein gives the name: »Cidaris variolata, § 7, Species III, 

 d'Acqueti, Tilrksche Tulband»-), an evident error already re- 

 marked by Leske. But this author, who never saw the col- 

 lection he commented on, but searched other collections for 

 specimens that seemed to him to agree with the figures of 

 Klein, in this instance pitched upon a species in the ca- 

 binet of Trier, widely diffcrent alike from the voblongo-teres» 

 of Seba and the »Tulband» of Schynvoet, and described it as 

 Cidaris subanp-ularis: »Ambitus orbicularis, forma fere hemi- 

 sphaerica .... taeniae poris per quatuor s. quinque paria ar- 

 cuatis» e. s. p. This being so, the name »subangnlaris», adop- 

 ted, though not without hesitation, by Desmoulins^) is to be 

 discarded.
