having some similarity to Thaumantias, but hardly referable to any of the established 

 families, — C. umbilicata n. sp. ; Phialidium allied to Thaumantias, P. viridicans n. 

 sp. ; Pyxidium truncatum n. sp., a singular form and difficult to assign the place of : 

 Paryphasma planiusculum, separated from iEquorea by the form and structure of 

 the arms, but described from specimens which had not attained their full develop- 

 ment. Thaumantias corollata, Oceania coccinea, Euphysa globator, Steenstrupia 

 lineata, Cunina moneta, C. costata are new species. (Gegenbaur) Studies of the 

 Organization and Classification of the Ctenophora; with three plates — p. 163-205. 

 A general review of what is known of this obscure group, with some new contribu- 

 tions to the history of their development, and to the classification. The family 

 Callianiridse is the most imperfectly known, and is placed at the head of the class 

 provisionally only. Of Calymnidse a new genus is characterized, Eurhamphcea, 

 with one species, E. vexilligera, new ; of Cydippidas, a new species Cydippe hormi~ 

 phora. To the families Cestidae and Beroidae there are no additions. Finally, 

 the author describes a new form, Sicyosoma rutilum, which he considers as repre- 

 senting the lowest type of the Ctenophora, wanting both the natatory plates and the 

 vascular system found in the rest of the Order. Extracts and Translations —
