parts, and the descriptive text is full, and accompanied with a copious 

 synonymy and references to other authors. We regret that our pres- 

 ent limits do not permit giving a full conspectus of the genera and 

 species of this group ; but ^q must content ourselves ■sv\\h giving only 

 the genera and the number of the species under each,

 Millita, (Klein,) 5 species. IV. Encope, (Agass.,) 11 species. V. Lo- 

 bophora, (Agass,,) 4 species. VI. Amphiope, (Agass.,) 2 species. 

 VII. Scutella, (Lam.,) 12 species. VIII. Echinarachinus, 4 species. 

 IX. Arachnoides, (Klein,) 1 species. X. Scutelleria, (Agass.,) 5 spe-

 11 species. XIII. Moulinia, (Agass.,) 1 species. 



Like all the works of this distinguished author, the present livraison 

 is marked by its great fidelity and the beauty of its mechanical execu- 

 tion ; and our constant wonder is, how Prof. Agassiz can carry on at 

 once so many great works as we know he has in hand, and yet devote 

 to each a measure of labor which few other naturalists can command 

 for a single object. 



We beg again to call the attention of American naturalists to the re- 

 quest of M. Agassiz, that all who are so disposed, will send him spe- 

 cimens of the Echinodermata of America, for which due acknowledg- 

 ment may be expected.
