the shores, ami in the future will doubtless afford a rich harvest of nov- 

 elties to the naturalists who investigate its treasures. The present 

 contribution to that branch of the subject is a mere beginning in a line 

 which promises rich results when more effectively explored. 



In conclusion I would express my appreciation of the facilities offered 

 by the authorities of the Fish Commission, the National Museum, and 

 the Smithsonian Institution in the preparation of this report. 



NOTES ON THE SPECIES COLLECTED. 

 Class BRACHIOPODA. 



The collection of Brachiopoda made on the voyage was small and of 

 little interest. Only one species, represented by two specimens, was an 

 addition to the Museum collection. The localities and data have a cer- 

 tain value for students of the group. 



Family EUDESIID^. 



Eudesia venosa Solander. 



This species was obtained from latitude 45° south, off the east coast 

 of South America, near Point Maiaspina southward to Magellan Straits, 

 in 20 to 80 fathoms, the temperature varying from 47° to 57° F. The 

 station numbers were 270!), 2770, 2772, 2775, 2777, 2778, and 2779. 



Eudesia fontaineana Orbigny. 



Terebratula foul a in can a Orb. Voy. Am. Mer., v., p. 675, No. 782, ix, pi. 85, figs. 30, 31. 

 Waldheimia venosa (pars) J),ill, Proc. Acad. Nat. Sci., Phil., p. 183, 1873, not of 

 Solander. 



Hab. — Station 2783, off the west coast of Patagonia, in south lat- 

 itude 51° 2', in 122 fathoms mud; bottom temperature 47°.9 F. 



This interesting species appears to be very rare; the only other spec- 

 imens I have heard of are the original types of Urbiguy, in the Paris 

 Museum, which I have never seen. His figure is excellent, but raiher 

 too inflated, which led me in 1873 to reler the species, though with some 

 doubt, to E. venom as a synonym. An examination of the present 

 specimens leaves no doubt of the validity of the species. Externally it 

 much resembles a large, smooth specimen of Terebratulina caputserpen- 

 Us var. septentrionalis. The ramifications of the sinuses are white and 

 form two bluut rather short channels on each side ot each valve. They 

 have no small attenuated divarications as in E. venom. The exterior is 

 mostly of a russet-brown color, but this may possibly be extraneous. 

 The soft parts and apophyses do not differ Iroui the usual type iu this 

 genus. 



Terebratella dorsata Gnielin. 



This species was, on the east coast of South America, not obtained 

 north of south latitude 52°, near Cape Virgins, but elsewhere was asso- 

 ciated with E. venosa and obtained through the same range of depth and
