 figs. 1-152. 

 In this article are described the 

 various species of nematodes, about 

 50 in number, which occur para- 

 sitic in the alimentary tract of 

 ruminants. The following species 

 are described as new : Strongy- 

 loides ovocinctus, Capillaria ore- 

 vipes, Capillaria longipes. 



The family Trichinellidw is di- 

 vided into 2 new subfamilies, Tri- 

 churinw and Trichinellinw. 



A new cestode from an African 



bustard.

 No. 1844, June 24, 1911, 

 pp. 637-647, figs. 1-7. 

 In this paper is described a new 

 species of tapeworm Sphyronco- 

 tmnia uncinata, the type of a new 

 genus belonging to the subfamily 

 Idiogenince, family Davaineidae, 

 superfamily Tcenioidea. The speci- 

 mens upon which the description 

 is based were collected by Mr. 

 Loring, of the Smithsonian Afri- 

 can Expedition, in British East 

 Africa from the intestine of a 

 bustard, Neotis caffra. 



ECHIN0DERMS. 



Clark, Austin Hobart. Proisocrinus, 

 a new genus of recent crinoids. 

 [Scientific results of the Philippine 

 cruise of the fisheries steamer "Alba- 

 tross," 1907-10.— No. 5.] 



Proc. V. 8. Nat. Mus., 38, 

 No. 1756, Aug. 6, 1910, 

 pp. 387-390, figs. 1-3. 

 The new genus Proisocrinus here- 

 in described includes a single spe- 

 cies, P. ruoerrimus, which is much 

 the tallest fixed recent crinoid yet 

 discovered, being slightly over 40 

 inches high". Its affinities are 

 clearly with the Pentacrinus mollis 

 described by P. H. Carpenter in 

 the Challenger report, but it is un- 

 certain whether it should be re- 

 ferred to the Pentacrinitidw , 

 Apiocrinidw, Bourgueticrinidce, or 

 Millericrinida. 



Thalassocrinus, a new genus of 



stalked crinoids from the East In- 

 dies. [Scientific results of the Phil- 

 ippine cruise of the fisheries steamer 

 "Albatross," 1907-10.— No. 7.] 



Clark, Austin Hobart — Continued. 



Proc. U. 8. Nat. Mus., 39, 

 No. 1793, Jan. 11, 1911, 

 pp. 473-476. 

 A new genus, Thalassocrinus, is 

 described which is related to Hyo- 

 crinus of the Antarctic, and to 

 GepJiyrocrinus of the eastern mid- 

 Atlantic. Thalassocrinus was 

 found by the " Albatross " among 

 the Philippine Islands. 



On the inorganic constituents of 



the skeletons of two recent crinoids. 

 Proc. V. 8. Nat. Mus., 39, 



No. 1795, Jan. 11, 1911, 



pp. 487, 488. 

 The analyses are here given of 

 the skeletons of a specimen of 

 Metacrinus rotundus from southern 

 Japan, and of a specimen of Heli- 

 ometra glacialis var. maxima from 

 the northern part of the Sea of 

 Japan. The proportion of MgCO 

 to CaCO was found to be approxi- 

 mately as determined previously 

 by H. W. Nichols in investigations 

 on the former.
