Anatomy, Reproduction, etc. 
Kocii (3) has studied the anatomy and histology of Tuhiporcn preserved 
in spirits. The walls of the polype and of its invaginated portion are 
composed of ectoderm, mesoderm [“ Stutzmemhran ”], and endoderm : the 
calcareous spicules are developed in the mesoderm ; muscular elements 
are only found in the tentacles (not in their pinnulae) and septa, on one 
side of which only they are however developed. All the septa have 
“ mesenteric filaments ” nearest to the “ pharynx ” ; in two of them, 
which are approximate and have their muscular layer on their opposed 
surfaces, the filaments are continued to the base ; in the other six, they 
are replaced by the generative capsules.

pp. 37-39. 
For anatomical details conoerjiuig Umhellula, Heteroxenia^ and Si- 
phonogorgia, cf. the papers of Kolliker (6) and Lindahl (8). P. 
Fischer has observed spontaneous fissiparity in Anemonia sulcata and 
Sagartia ignea, and reproduction by small fragments left by the foot, in 
S. pellucida ; C.R. Ixxix. p. 1210. 
A. Agassiz briefly reviews an important paper (in Russian, not seen 
by the Recorder) by A. Kowalewsky, on the embryology of various 
Ccelenterata {Campanularia^ RJiizostoma, Cassiopea, Pelagiay Actinia, A l- 
cyoniuni, Astrcca, Gorgonia, Cerianthus, Eschscholtzia, Beroe, Eucharis) ;

PouRTAL^s (9) enumerates the deep-sea corals collected on the 
“ Hassler” expedition, especially off Barbadoes, a few also oft Brazil and 
Juan Fernandez ; those collected by the late W. Stimpson in the 
waters of Florida, Ouba, and Yucatan are also recorded. The species 
described or figured are enumerated below. The existing West 
Indian fauna of deep-sea corals agrees much more with the corres- 
ponding recent and tertiary European fauna than with the tertiary West 
Indian. P. Fischer enumerates 31 species oi A ctmiidcc, 4 of corals, and 
3 of Gorgo7iiidce from the west coast of France ; of the former 25
