FIolotype.—{V. S. Nat. Mus. No. 12612.) From Albatross D5178, 

 in 78 fathoms off Romblon, P. I. 



It also occurs in the Philippines from the following stations: D5143, 

 19 fathoms and D5144, 19 fathoms, both off Jolo Jolo; D5152, 34 

 fathoms, Tawi Tawi group; D5268, 170 fathoms, Verde Island Pas- 

 sage; D5319, 340 fathoms, China Sea off Formosa. It also occurs at 

 D4883, 53 fathoms, oft' Japan. We have specimens from off the 

 Poor Knights Islands, New Zealand, in 60 fathoms, and from Van 

 Diemans Inlet, Gulf of Carpenteria, Queensland, Australia, 10 

 fathoms. There are specimens in the collection from the lower 

 Pliocene of Beaumaris, near Melbourne, Victoria, Australia. 



The species is named after Dr. Paul Bartsch, of the United States 

 National Museum, who collected much of the material in the Albatross 

 cruise in the Philippines. 



In general outline, Guttulina bartschi is similar to Guttulina regina 

 distributed in the Indo-Australian region; but G. bartschi has a smooth 

 surface.

 Res., vol. 4, 1928, p. 15, pi. 2, fig. 1; Jap. Journ. Geol. Geogr., vol. 6,

Test ovate to broadly fusiform, greatest breadth usually slightly 

 below the middle, base broadly rounded; chambers inflated, clavate, 

 arranged in a clockwise, quinqueloculine series, each succeeding 

 chamber farther removed from the base; sutures only slightly de- 

 pressed, distinct; wall smooth, polished, thick; aperture radiate. 



Length of adult specimens, 1.00-1.42 mm.; breadth, 0.65-0.83 mm.; 

 thickness, 0.55-0.69 mm. 



Guttulina orientalis most closely resembles Guttulina problema, from 

 which it is distinguished by its more inflated chambers arranged much 

 closer in a quinqueloculine series, and each succeeding chamber is 

 removed much farther from the base. From Guttulina austriaca it 

 is easily separated by its less depressed sutures, more rounded base, 

 and inflated chambers. 



Distribution. — The species occurs at numerous localities about 

 Japan. The type locality is from the upper Pliocene of Sawane, 

 Island of Sado, Japan. It occurs also in the upper Pliocene of Nat- 

 sukawa, and there are numerous Recent specimens from off Kobama. 

 In the Albatross dredgings, it occurs at D4826, 114 fathoms, D4843, 

 100 fathoms, both off Japan. 



In addition, there is in the collection a single specimen of similar 

 form in Doctor Bagg's material from Timms Point, Calif. It may be 

 noted also that we have a very few specimens from the Miocene of
