772-995 fathoms. 



The narrow stolon-like connections between the chambers make 

 the test ver} 7 fragile and probably account for the fact that specimens 

 with slender connections are composed of few chambers. Goes's 

 figures are very small and it is difficult to deter- 

 mine exactly what he had. Goes's figures of R. 

 pilulifer are apparently R. guttifer, as near as one 

 can make out. 



REOPHAX INSECTUS Goes. 



Reophax insectus Goes, Bull. Mus. Comp. Zool., vol. 29, 

 1896, p. 28, pi. 3, figs. 6,7. 



Description. — Test stout, tapering, consisting of 



several short, inflated chambers, each larger than 



the preceding one, wall composed of large sand 



grains and rather rough on the exterior ; circular in 



end view; light gray in color. 



Length 5-8 mm., the last chamber often 2 mm. 



in diameter. 



Distribution. — Goes described this species from 



material from Albatross stations off the west coast 



of Mexico and near the Galapagos Islands, Alba 



tross stations D3407, D3419, and D3431, in 



Besides seeing the original material and 

 finding additional specimens at the last 

 station, I have found two specimens from 

 Albatross station D4337, in 617-6S0 

 fathoms off San Diego, California. The 

 > ^i W material from this station was very 



similar to that from farther south, and 

 might equally well be termed "Rhab- 

 dammina ooze." 



REOPHAX ADUNCUS H.B.Brady. 



Reophax adunca IT. B. Brady, Proc. Roy. 

 Soc. Edinburgh, vol. 11, 1S82, p. 715; 

 Rep. Voy. Challenger, Zoology, vol. 9, 

 18S4, p. 296, pi. 31, figs. 23-26.— Flint, 

 Rep. U. S. Nat. Mus., 1897 (1899), p. 

 274, pi. 18, fig. 5. 



Description. — Test consisting of sev- 

 eral subglobular chambers in an irregu- 

 lar line, constrictions between the cham- 

 bers slight, walls thin, composed of rather coarse sand grains giving 

 a rough exterior, length indefinite, 2 mm. or more. 



Distribution. — The only North Pacific records for this species are 

 from Challenger stations 237, 244, 246, and 256, 1,875-2,950 fathoms, 

 all curiously enough between lat. 30° and 40° N.
