Science (n. s.), xxix. No. 



747, April 23, 1909, p. 



077. 



The probable attitude of Uinta- 



crinus when living is discussed, 



and the ecological value of certain 



types of coloration suggested.

genus of uustalked crinoids. 



Proc. U. 8. A'at. Mus.. 



XXXVI, No. 1668, April

 Philippine Islands, is treated in 

 detail ; 9 new species are de- 

 scribed, belonging to the genera 

 Phanogenia, Comanthus, Pontio- 

 mctra, Cenometra, Ptilomctrn, 

 Stenotnctra, Crotalomctra (n.

Expedition. 



Zool. Aiueiger, xxxiv, Nos.

 363-370. 

 The crinoids collected by the 

 German steamer Gazelle on the 

 west coast of Australia and at 

 Timor and New Guinea are dis- 

 cussed in detail. A discussion of 

 the faunal relations of Australia, 



Clark, Austin Hobart — Continued. 



and a complete biblography of 

 works on Australian crinoids, are

Comasterldpe, with descriptions of 

 new genera and species. 



Proc. U. 8. Xat. Mus., 



XXXVI, No. 1685, June 7, 



1909, pp. 493-507. 



The history of the family Comas- 



teridae — the genus Actinometra of 



P. H. Carpenter— is discussed, 



and the family is shown to be 



divisible into 11 definite generic 



types : 5 new genera and 3 new 



species (types of new genera) are 



described. 



Descriptions of seventeen new 



species of recent crinoids. 



Proc. V. S. ^'at. Mus., 

 XXXVI, No. 1691, June 19, 

 1909, pp. 633-651. 

 Descriptions are given of a 

 number of new crinoids dredged 

 by the Investigator, co-types of 

 which have been deposited in the 

 U. S. National Museum, together 

 with those of a few species col- 

 lected by the Albatross. 



Four new species of the crinoid 



genus Rhizocrinus. 



Proc. U. S. Nat. Mus., 

 XXXVI, No. 1693, June 

 19, 1909, pp. 673-676. 

 The genus Rhizocrinus is shown 

 to consist, not of two very variable 

 species, with a very great geo- 

 graphical and bathymetrical range, 

 as supposed by Carpenter, but of 

 several very constant species, each 

 occupying a comparatively small 

 range. Four new West Indian spe- 

 cies are described. 



New recent Indian crinoids. 



Proc. Biol. Soc. Wash.,

 Sixteen new crinoids, mainly 

 from the collections made by the 

 Royal Indian Surveying steamer 

 Investigator, are described, as fol- 

 lows : In the family Comasteridae, 

 one species each of Comatula and 

 Comastcr ; in the Himerometridae, 

 one of Mariametra (n. gen.) ; in 

 the Colobometridae, two of Ceno- 

 metra and one of Ci/Uometra ; in 

 the Tropiometrida^, two of Astero- 

 metra ; in the Thalassometrida\ 

 one each of Crotalomctra, Tluilas-
