144 (in text). 



Test elongate, subcyKndrical, composed of numerous chambers which are 

 not distinct from the outside, the main ornamentation of the surface con- 

 sisting of longitudinal costae, usually somewhat spirally twisted, running from 

 the initial end to the aperture; the aperture itself rounded, in the center of 

 the obHque, apGrtural face; the costae of the surface running in to the center, 

 making a radiate pattern about the aperture itseK; color white. 



Length of the Tortugas specimen 0.4 mm. 



This species is one of the "finds" of the Tortugas collection. It 

 has not previously been recorded from the Atlantic. So far as known, 

 its distribution has been from shallow water of the Indo-Pacific 

 region. Brady, in the Challenger Report, gave seven localities for 

 this, as follows: "Port Stephens and Port Jackson, New South 

 Wales, 2-10 fathoms; off Levuka, Fiji, 12 fathoms; off the New 

 Hebrides, 125 fathoms; Torres Strait, 155 fathoms; Humboldt Bay, 

 Papua, 37 fathoms; Nares Harbour, Admiralty Islands, 17 fathoms." 

 Millett's specimens came from two stations in the Malay region. 

 Bagg recorded this species from a single Albatross station, H4694, in 

 865 fathoms, off the Hawaiian Islands, and in 1911 I added another 

 station, H2922, in 268 fathoms, ofif the same Islands. The other 

 record is from the Kerimba Archipelago, off the eastern coast of 

 Africa, where Heron-Allen and Earland recorded it. Its natural 

 habitat is evidently in comparatively shallow water in tropical seas. 

 It is a small species and one that is apt to be overlooked, and it may 

 be fairly common in the Caribbean and the Gulf of Mexico, although 

 it was certainly rare in the Tortugas region. 



Genus VIRGULINA d'Orbigny, 1826. 



Virgulina punctata d'Orbigny. 



(Plate 3, Figure 9.) 



Virgulina punctata d'Orbigny, in De la Sagra, Hist. Fis. Pol. Nat. Cuba, 1839, "Forami- 

 nif^res," p. 139, pi. 1, figs. 35, 36. — Cushman, Proc. U. S. Nat. Mus., vol. 59, 

 1921, p. 52. pi. 11, fig. 15. 



Virgulina squammosa Cushman, (not d'Orbigny, 1826), Carnegie Inst. Wash. Pub. 213, 1918, 

 p. 284. 



Test elongate, fusiform, broadest near the middle, the initial end bluntly 

 pointed, composed of numerous chambers, the earliest few triserial, those of 

 the adult portion irregularly biserial; chambers somewhat inflated; sutures 

 sUghtly depressed, distinct; wall smooth, punctate, especially in the earlier 

 portion, the later chambers being usually clear, except for punctations near 

 the lower edge; aperture elongate, connecting with the previous aperture by 

 a tubular connection; color white. 



Length of the Tortugas specimens rarely exceeding 0.5 mm.
