of a flagellate protozoan cell, the ancestor of the colony of cells from 
which the metazoan body is believed to have taken its origin. Thus 
zur Strassen regards the polarity of epithelial cells not as a newly 
acquired feature, but as an inherited one derived from forms as 
primitive, possibly, as the protozoa. P. 
The Intestine of Cetaceans. — Süssbach! has described in detail 
the structure of the intestine in a number of cetacean embryos 
recently collected by Kükenthal. In the toothed whales there is no 
division into a large and small intestine, and, except in Platanista, 
there is no ccecum present, structural conditions always observed in 
the baleen whales. 'The toothed whales always possess a simple 
mesentery, without any trace of the complications introduced in the 
baleen whales by the folding of the intestine about parts of the mes- 
entery. The toothed whales have a relatively longer intestine than 
the baleen whales, but the configuration of the intestinal surface 
seems to be independent for the two groups; thus some of the 
toothed whales with short intestines have much the same kind of 
Intestinal surface as that in the baleen whales, though a general rule 
Was found to the effect that the shorter the intestine is, the more 
complicated are the folds on its surface. Notwithstanding this last 
circumstance, the condition of the intestine points to the complete 
separateness of the two groups of living cetaceans, the baleen and 
the toothed whales. — P 
Notes on Recent Fish Literature. — In the Proceedings of the 
California Academy of Sciences (Zool, Vol. II, Nos. 7, 8) Jordan 
and Snyder describe two very remarkable new genera of Japanese 
fishes, The one, Ereunias (grallator), is a cottoid, allied to Trig- 
lops, but without ventrals, and with the four lowermost pectoral 
Tays developed as detached feelers, as in Trigla. The other genus, 
seus (sachi), is like Podothecus, but with enormously developed 
orsal and anal fins. It belongs to the Agonidz. 
= e same Procedings Jordan and Starks describe three new 
due an Japan, Snyderina Jyamano&ami, Pomacentrus celestis, and 
c Doer deani. Snyderina is a new genus of Scorpznidse, allied 
la osopodasys. All these species are represented by admirable 
P'ates, the work of Mrs, Chloe Lesley Starks.
