developed a median furrow on each value in adaptation to the body form 
of Gebia. An interesting case was observed in which an otherwise nearly 
smooth Placuanomia shell had assumed during its growth the concentric 
raised lines of a Saxidomus valve upon which it was attached. 
The insects are not very abundant, they are represented in the collection 
mainly by a tew wood beetles, myriopods (Julus, Polydesmus,) and 
a species of Termes. 
Mr. Carkıns reported on the Protozoa and Coelenterates of Puget 
Sound and of the Alaskan Bays. 
The Protozoa and Coelenterates collected during the summer by 
Mr. Catxins belong chiefly to the group Flagellata for the former, and to 
the Leptomedusae for the latter. In addition, there are 9 species of 
Hydroids — a large number considering the very limited representation 
of this group in the western waters. Twelve or fourteen species of 
Actinians and about the same number of Sponges, and several Scypho- 
medusae complete the list of Coelenterates. 
Mr. Basurorp Dean reported on the Chordates and Protochordates of 
the collection. The Ascidians are represented by about a dozen species, 
Fishes by upwards of forty. The most important part of his work had 
been the collecting of embryos and larvae of Chimaera (Hydrolagus colliei) 
and a fairly complete series of embryos of Bdellostoma, including upwards 
of 20 stages from cleavage to hatching. Of Chimaera upward of eighty 
egg cases had been dredged in a single day; but in every case these were 
found to be empty. The eggs were finally obtained at Pacific Grove, 
California, from the gravid and were incubated in submerged cages. It 
was in this locality that the eggs of Bdellostoma were collected.
