TROPICAL PACIFIC FORAMmiFERA OF "ALBATROSS" 37 



Test elongate, somewhat compressed, peripheiy lobed, early portion 

 tapering, remainder of the test with the breadth rather uniform; 

 chambers distinct, the early ones rather uniformly increasing in size 

 as added, later ones becoming more mflated and more distinctly 

 separated ; sutures distinct, depressed, strongly oblique, nearly straight; 

 wall ornamented by a distinct raised ridge somewhat above the suture, 

 the periphery of which is often toothed and the later chambers some- 

 what roughened; aperture elongate, terminal in the adult, with a 

 slight lip. Length, 0.75 mm.; breadth, 0.40 mm..; thickness, 0.25 

 mm. 



Most of the records for this species are from the Indo-Pacific region. 

 The types were from off New Guinea. There are a number of other 

 records from this same general region some of which have no figures 

 accompanying them. There are also other records for the species 

 from other areas both fossil and Recent, but the figures accompanying 

 these records show rather distinctly that they are not the same as this 

 Indo-Pacific species of Brady. The only specimen of this species 

 that we have from this area is from the Paumotu Islands, Albatross 

 station H3870, village, point of Anaa Atoll, S. 50°, 5 miles west, in 

 1,110 fathoms, 36.0° F., fne.co.s.pter.oz.glob.

Loxostoma vertebrate Cushman (in part), ibid., p. 194. 



Test very elongate, slender, about 4 times as long as broad, periph- 

 ery serrate in front view, rounded in end view; chambers distinct, 

 inflated, as high as broad throughout, early ones smooth except for a 

 spine at the peripheral angle, later ones very deeply excavated on the 

 lower side and crenulate at the border, tending to become somewhat 

 uniserial in the adult; sutures distinct, depressed, very strongly so in 

 the adult, oblique; wall of early portion smooth, later portion smooth 

 except for the crenulate border; aperture elongate, oval, with a dis- 

 tinct lip, tending to become terminal. 



This species is close to L. vertebrate (Cushman), and the two may be 

 easily confused. L. convallarium occurs in our shallow water collec- 

 tions from off Fiji, 40-50 fathoms; oft" Nairai, 12 fathoms; off Levuka, 

 12 fathoms; and Rotonga, 7 fathoms.
