or that WILLIAMSON'S specimens belong to Hyas coarctatus. His de- 
termination, by the way, is not put forward with absolute certainty; 
but carefully stated thus: “this species is, I consider, Hyas araneus”’. 
The Megalopa stage of the two species on the other hand exhibits 
certain differences, as will be seen by comparing WILLIAMSON |. c., 
р. 15, fig. 2, with W. Взбвск, Biolog. faunistisch. Untersuch. Öresund 
(Lunds Universitets Ärsskrift, N. F., Afd. 2, vol. 9, Nr. 17), 1913, p. 22, 
text fig. 1—2.

A. The adult stage. 
Kvanefjord St. 4, 20,5—34 m., 1 spec. — Bredefjord St. 40, 
170—180 m., 1 spec. — Skovfjord St. 156, 70—140 m., 2 spec. 
B. The larva (G. O. Sars, Decapodernes Forvandlinger 2; Ar- 
chiv for Math. og Naturvid., Christiania, 1889, p. 154, Pl. 2, fig. 29). 
Bredefjord St. 59, ringtrawl, 300 m. w., Zoea, 1 spec.; St. 66, 
9—11 m., Zoea, 1 spec. 
This species has been found in W. Greenland from Julianehaab 
to Umanak Fjord (abt. 71° N.). 
x 5. Munida Bamifica Penn? 
Munida Bamffica H. J. Hansen, Crustacea Malacostraca; The 
Danish “Ingolf” Exped., vol. 3, pt. 2, 1908, p. 32 (ubi lit. et syn.). 
Bredefjord St. 31, rmgtrawl, 700 m w., 2 spec. (Zoea). 
Two specimens of a Zoea stage of this species were obtained at this 
station; they are very similar to, and probably identical with that de- 
scribed by Sars as 1. Zoea (Decapodernes Forvandl. 2, Archiv f. Math. 
og Naturvid., Christiania, 1889, р. 178, Pl. 6, fig. 1—11. (Munida ru- 
gosa)). 
Neither full-grown nor larval stages of this species have hitherto 
been found in true Greenland waters; the nearest locality at which it 
has been taken (full-grown) is W. of Iceland (H. J. Hansen |. c., p. 32), 
while the larva was found by the “Tjalfe’”’ expedition somewhere between 
Iceland and Greenland. 
5b. Munida sp. (M. Bamffica?). (Fig. 2). 
Together with the two larvae of Munida Bamffica already mentio- 
ned, the “Rink” obtained two somewhat older Munida larvae, possibly 
belonging to the same species, both having teeth on the dorsal side of 
the 4—5 abdominal segment, such teeth not being found in the larva 
of M. tenuimana (vide my work on the “Tjalfe’” expedition, р. 130, fig. 
55—55). The length is 8 mm. Antennae and mxp. 1—2 have the same 
form as in the young larva of M. tenuimana ("Tjalfe” exped., fig. 35); 
in mxp. 3, however, the exopodite is quite small, as are also pl—pd.
