43, figs. 31—39, I have described a larva taken in Danmarks Havn 
(ca. 77° N, E. Greenland), O — 20 m., 19—9—1907. 
Unfortunately tke Danmark Expedition has taken but a single, 
badly preserved specimen. The specimens from the “Tjalfe” are 
better preserved and show, that the telson has a little spine at 
the hind corner. There is a little difference in regard to the man- 
dibles, and the fiagellum in the 2nd antenna has no trace of ar- 
ticulation; in all other regards the specimens from the “Tjalfe’' 
fully correspond with that from the Danmark-Expedition. In the 
specimen figured the uropoda are somewhat shorter than the telson; 
in the other specimens they have the same length as the telson. 
Krachyurid larva, lst Zoea (fig. 33). 
(St. 19a) 58°41'N, 49° 44' W, 100 m. wire, 31—5—1908, 1 spec.

At the localities mentioned above the lst Zoeastage of a 
crab was taken. The larvæ are in some points very like the larva 
of Hyas araneus (Williamson, Eep. on larval and later stages of 
certain decapod Crustacea: Fisheries, Scotland, Sci. Invest. 1909, 1. 
(Decbr. 1910), p. 13—15, PI. 1, figs. 1—2; PI. 5, figs. 70—78, 80—81).

In other points they are very like the lst Zoea of Cancer pagurus 
(J. Pearson, Cancer; Transact. Liverpool Biol. Soc., vol. 22, 1908 
p. 461, PI. 13, figs. 85—87); the appendages are in about the 
same stage of development, and the telson has about the same 
form and the same number of spines: but the lateral spines of the 
carapace of the larvæ from the “Tjalfe” are longer, and on the 
abdominal segments there are lateral spines as in the larvæ of
