REPORT OF NATIONAL MUSEUM, 1919. 



Merriam, C. Hart. Two new manza- 

 nitas from the Sierra Nevada of 



California. 



Proc. Biol. Soc. Washington, 

 vol. 31, July 10, 1918, pp. 

 101-103, pis. 2-5. 



Mkrrit.l, George P. Further notes on 



the Plainview, Tex., meteorite. 



Proc. V. S. Nat. Mus., vol. 

 54, no. 2243, Oct. 7, 1918, 

 pp. 503-505, pis. 79, 80. 

 Takes up again the subject of 

 the apparent brecciated structure 

 referred to in the first paper rela- 

 tive to this stone, and shows with 

 apparent conclusiveness that the 

 stone is composed of fragments of 

 two stones differing from each 

 other in a marked degree in their 

 relative richness in chondrites. 



On the Fayette County. Tex., 



meteorite finds of 1878 and 1900 and 

 the probability of their representing 

 two distinct falls. 



Proc. V. 8. Nat. Mus., vol. 

 54, no. 2248, Nov. 25, 

 1918, pp. 557-561, pis. 86, 

 87, 1 fig. 

 Gives the results of careful mi- 

 croscopic study of these stones and 

 shows v/ith seeming conclusiveness 

 that they are not, as was first sup- 

 posed, identical, but represent two 

 distinct falls. 



Lazulite in an unusual form. 



Amer. Mineralogist, vol. 3, 

 no. 11, Nov., 1918, p. 192. 

 A brief note only, calling atten- 

 tion to the occurrence of this min- 

 eral replacing the original rock 

 fragments in what was apparently 

 a volcanic breccia. 



The percentage number of 



meteorite falls and finds considered 

 with reference to their varying basic- 

 ity. 



Proc. Nat. Acad. Sci., vol. 5, 

 Feb., 1919, pp. 37-39. 

 This paper calls attention to the 

 very interesting change in the 

 character of meteorites noted iu 

 the observed falls. But 5 per cent 

 of the known meteoric irons, 16 

 per cent of the mesosiderites, and 

 25 per cent of the howardites and 

 ureiiites have been seen to fall, 

 against 95 to 100 per cent of acidic 

 types grouped under the chondrule- 

 free types. 



Merrill, George P. A heretofore un- 

 described meteoric stone from Kan- 

 sas City, Missouri, 



Proc. U. 8. Nat. Mus., vol. 

 55, no. 2259, Apr. 12, 

 1919, pp. 95, 96, pis. 1, 2. 

 Briefly describes a meteoric 

 stone in the collection of the 

 Daniel B. Dyer Museum of Kan- 

 sas City, Mo., attention to which 

 has been called by Mr. Edward 

 Butts, the Curator. This stone 

 was found in 1903 but its me- 

 teoric nature, while suspected, was 

 not fully recognized. 



Metcalf, Maynaed M. assisted by 

 Mary M. Bell. The Salpidae col- 

 lected by the United States Fisheries 

 steamer Albatross in Pliilippine 

 waters during the years 1908 and 



1909. 



Bull. U. 8. Nat. Mu,9., no. 



100, vol. 2, pt. 1, May 



7, 1919, pp. 1-4. 



This paper lists the 98 lots of 



Salpidae secured by the AWatross 



in Philippine waters, embracing 11 



species and 1 new variety. 



Tlie Salpidae: a taxonomic 



study. 



Bull. U. 8. Nat. Mus., no. 



100, vol. 2, pt. 2, Apr. 



29, 1919, pp. 1-193, pis. 



1-14, text, figs. 1-150. 

 This monograph presents a sys- 

 tematic report on the Salpidae 

 giving an exhaustive taxonomic 

 diagnosis of each species with a do- 

 tailed discussion of both the soli- 

 tary and aggregate forms thereof, 

 concluding with a summarized 

 discussion of the relationships 

 among the Salpidae as exempli- 

 fied by these studies. A list of 

 unidentifiable species of doubtful 

 validity is appended with annota- 

 tions. A key to the Salpidae is 

 also given.
