 the Thalassicollae, Polycvstinese, and Acanthometra?, of the Mediterranean — p. 

 474-503. The author retains Meyen's name Sphaerozoum for the compound form 

 Thalasdcolla punctata Hurley. Another compound form, with reticulated shells, 

 he calls Collosphcera ; the name Thalassicolla being retained for the solitary 

 forms, such as T. nucleata H., distinguished from Polycystinea by the absence of . 

 a siliceous shell, and from Acanthometra by not possessing siliceous spicula. Two 

 new species of Sphaerozoum are noticed. Several new forms of Polycystinese are 

 characterized, Lithocircus, Cladococcus, Acanthodesmia, Dictyosoma, and many 

 new species. Of Acanthometra fourteen species are distinguished, and A. arach- 

 noides Claparede constitutes a new genus Plagiacantha. Many observations on the 

 structure and movements of these creatures are added ; but of the mode in which 

 they take food nothing is yet ascertained. In one case the interior of an Acantho- 

 metra was seen full of little particles in lively motion, from an examination of 

 which Mueller is inclined to think that the young resemble the jjarent, except in 

 wanting spicula and in their activity. (Schacht) Fructification of Phanerogama,
