518 THE VOYAGE OF H.M.S. CHALLENGER. 



Amphpoda. It was discovered by Captain Phipps in 1773, and is found along the shores 

 of Arctic America, in the White Sea, on the coasts of Greenland, Iceland, Spitzbergen, 

 Norway, and in the Sea of Okhotsk" (p. 309). On the following day Captain Markham 

 with his party, by a walk of about a mile, reached latitude 83° 20' 26" N., 399i miles from 

 the North Pole.

The first section is on the unicellular glands in the first and second peroeopods of the 

 Corophiidae. Counting seven joints to the leg, the gland-cells are found as a rule in the 

 second, third, fourth and fifth joints. Each single element of the gland presents itself as 

 one cell, with a special cuticular duct, hence the epithet chosen. There are two kinds of 

 cells, the opaque and the clear, the former found only in the second joint, the latter both 

 in this and the three following. 



In the unguis there is a little reservoir into which the ducts of the glandular apparatus open to 

 let out the house-builJing secretion at the point of the finger. The form of the glandular 

 complex varies, but for the same species, or even genus, is constant. Nebeski found the 

 secretory apparatus in all Corophiidse which he was able to examine ; " these were species 

 of the genera Microdeutopus, Microprotoptis, Amphithoe, Podocerus, Cerapus and CoropMum. 

 The genus Cyrtophium, which hitherto has been included among the Corophiida^, but which 

 is devoid of the glands and so appears to be an exception, diflfers in many respects 

 essentially from the Corophiidse, and on the other hand stands so near to the Dulichiidaj 

 that it ought to be reckoned in this family, and so the exception is only apparent." In 

 Ofchestia the arrangement is different ; in the Gammaridse, he says, the glands are, so far as 

 he knows, entirely wanting. He considers that the possession of the secretory apparatus in 

 the first and second perasopods may be regarded as the characteristic mark of the Corophiid*. 

 " It has been long known," he says, " that species of the genera Cempiis, Sipho7wcmtes and 

 Undola, Say { = Microdeutopus, Costa) through cementing sand, mud, particles of wood, 

 etc., by means of a secretion hardening in water, form tubes into which they withdraw
