land”, in.,,Meddelelser om Grønland", vol. 45, 1912, p. 522, Pl. 
43, figs. 31—39, I have described a larva taken in Danmarks Havn 
(ca. 77? N, E. Greenland), 0—20 m., 19—9—1907. 
Unfortunately the 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 flagellum 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.

At the localities mentioned above the 1st Zoeastage of a 
Crab was taken. The larvæ are in some points very like the larva 
of Hyas araneus (Williamson, Rep. on larval and later stages of 
certain decapod Crustacea: Fisheries, Scotland, Sci. Invest. 1909, 1. 
(Decbr. 1910), p. 13—15, Pl. 1, figs. 1—2; Pl. 5, figs. 70—78, 80—81). 
In other points they are very like the 1st Zoea of Cancer pagurus 
(J. Pearson, Cancer; Transact. Liverpool Biol. Soc., vol. 22, 1908 
p. 461, Pl. 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
