Eucopia sculpticauda Faxon, Bull. Mus. Harvard, 24, 1893, 218. Faxon, Mem. Mus. Harvard, 18, 
219,- pi. K, f. 2, pi. 53 f. b; 1895. Hansen, Bull. Mus. Ocean. Monaco, 30, 1905, 7, fig. 4. 
With the female from station 4005 were the following notes about color: 
“The carapace is very deep, velvety, port-wine red or “purple,” so intense as to appear almost 
black in poor light, extending caudad along dorsum of abdomen, shading off to deep carmine on rest 
of abdomen, including swimmerets and telson, which is a trifle lighter. Appendages of head and 
thorax: Long legs, madder carmine; short appendages, deep port-wine red; antenna, madder pink; 
exopodite, bright carmine; antennule, bright carmine.” 
Stations: 4005, 577-480 fathoms, 1 female, and 4144, 850-767 fathoms, 1 male, from vicinity of Kauai 
Island. 
Distribution. — Gulf of Panama, 1,000 fathoms, and Galapagos Islands, 885 and 1,360 fathoms; sub-

Family MYSIDAE Dana. 
Genus PETALOPHTHALMUS Willemoes-Suhm. 
17. Petalophthalmus pacificus Faxon. 
Petalophthalmus pacificus Faxon, Bull. Mus. Harvard, 24, 1893, 218. Faxon, Mem. Mus. Harvard, 
18, 1895, 223, pi. 54. 
Our specimen agrees absolutely with Faxon’s species. 
Station 4157, 762-1,000 fathoms, vicinity of Modu Manu, 1 male. 
Distribution. — Gulf of California, 0-700 fathoms. 
Genus BOREOMYSIS G. 0. Sars. 
18. Boreomysis obtusata G. O. Sars. 
Boreomysis obtusata G. O. Sars, Rep. Voy. Challenger, 13, 182, pi. 33, f. 1-6, 1885. 
Although not well preserved, the specimens agree clearly with this species. Sars says that the 
eyes have a dark reddish pigment; in our specimens the eyes are pale brown, which possibly is due 
to the action of the alcohol. The female from station 4014 has lost both eyes. 
Stations: 4014, 399-362 fathoms, 1 male, 1 female; and 4018, 804-724 fathoms, 1 male; both from 
vicinity of Kauai Island. 
Distribution. — Off coast of Japan, 35° 11 / N., 139° 28 / E., 345 fathoms, and north of Hawaiian 
Islands, 37° 52' N., 160° 17 / W., 2,740 fathoms. 
Genus SIRIELLA Dana.« 
19. Siriella thompsoni ( Milne-Ed wards) . 
Siriella thompsoni, G. O. Sars, Rep. Voy. Challenger, 13, 205, pi. 36, f. 1-24, 1885. Ortmann, Decap. 
■& Schizop. Plankton Exped., 23, 1893; Bull. Mus. Harvard, 25, 1894, 107. 
The specimens (females) from station 3799 were marked : “Hyacinth blue eggs, body translucent.” 
Stations: 3797, surface, Erben Bank to Kaiwi Channel, 31° 55' N., 136° W., 12 males, 8 females; 
a Norman (Ann. Nat. Hist. (6) 10, 1892, p. 149) abandoned Siriella Dana in favor of Cynthilia Gray, June 15, 1850, but 
later (ibid., p. 263) restored it, Siriella having been published by Dana in the early part of 1850. This latter correction has 
been overlooked by Ehrenbaum (Beitr. Meeres. Helgoland 8, 1897, p. 424).
