large glands on each side of the stomach, of a pi color, and

Fisnes.—Dr. H. H. Giglioli, of the Royal Museum of Florence, 
records (Nature, XXXVIII., 103) the receipt of the sixth known 
specimen of the rare Lepidosiren paradoxa, which for many years 
was only represented by Natterer’s original specimens. The present 
individual was taken at Antaz, near the Madeira River, in Septem- 
ber, 1887, and when received was in a state of incipient decomposi- 
tion. Mr. G. B. Howes communicates a note on the same subject 
(Le., p. 126), calling attention to the specimen recorded by Bibron 
and Milne-Edwards in 1840. 
Professor C. T. Lutken has recently ( Vidensk. Selsk. Skr. Kjob., 
IV.) described the skeleton and some other parts of the deep-sea 
toad-fish Himantolophus. Comparisons are made with Ceratias. 
According to Prof. D. S. Jordan ‘and B. W. Evermann, 
there are about 150 species of fishes known in the waters of 
Indiana, and about fifty of these may be regarded as food-fishes. 
Of the remaining kinds, some ten are large enough for food, but 
for one reason or another are not used. The flesh of the paddle- 
fish and shovel-nosed sturgeon is poor and tough, that of the gar- 
pikes is not eatable, while the hickory shad and skip-jack are 
valueless on account of their dry thin flesh, full of small bones. 
he cisco of the deep lakes of Northern Indiana and Wisconsin, 
formerly thought by Prof. Jordan to be distinct from the leak 
herring, and named by him Argyrosomus sisco, is now held by, the 
same authority to be only a local variety of Coregonus artedi modi- 
fied by residence in the smaller lakes. 
„Dr. A. Gunther (Ann. and Mag. Nat. Hist., June, 1888) describes 
nine new species of fishes from the Yangtsze-kiang, collected at or 
near Ichang, One of these, Eleotris zanthi, belongs to the spine- 
finned section, the others are Cyprinide or Cobitidina. 
I. R. Storms has, in an article in the Annals and Magazine of 
Nat. Hist, for J uly last, attempted to solve the questions pertaining 
to the structure and morphology of the disk of the remora. 
e disk is a modified spinous dorsal, and not of dermal origin, he 
believes to be proved : (1), by its position; (2), by the slight trans- 
formation of the interneural spines; (3), by the presence of the 
changed, yet recognizable elements of a normal spinous dorsal fin. 
A typical segment of the spinous dorsal of Scomber has three
