General Remarks. 
Tiie most important work of the year is Schulze’s account (34) of the 
structure and classification of the Hexactinellida ; nothing approaching it 
in clearness and completeness has appeared since the “ Kalkschwamme ” 
of Haeckel; a long abstract is given on pp. 10-15. Next in interest to 
the general zoologist is Heider’s detailed and complete description of the 
development of Oscar ella lobularis, Sdt. ; of this (12) a full abstract is 
given on pp. 6-9. Ridley & Dendy (33) publish a preliminary Report of 
the ‘ Challenger ’ Monaxonids, with a revised classification of the group ; 
an abstract appears on pp. 16-19. Yosmaer (41) concludes his important 
work on the Povifcra in Bronn’s Thierreichs. Attention is also directed 
to Lendenfeld’s description of the vestibule of Raphyrus liixonii , n. sp., 
in which he discovers another instance of a nervous structure in Sponges ; 
to Dendy & Ridley’s (4) description of ProteUia sollasi , n. g. & sp., a 
Suberite in which Tetractinellid-like anatriaenes occur ; and, finally, to 
Goette’s account of the development of Spongilla Jluviatilis. The 
remaining papers are of special rather than general interest.
