292 RECORD OF SCIENCE FOR 1887 AND 1888. 



Miss Mary B. Holmes (110) has prepared a paper beautifully illus- 

 trating the "morphology of the cariiune upon the septa of rugose corals," 

 presented as a thesis for the degree of doctor of philosophy in the Uni- 

 versity of Michigan. A short notice of this paper is given in the Amer- 

 ican Geologist, vol. i, p. 61. I have seen the drawings, but have not 

 read the paper. 



CRINOirS. 



Wachsmuth and Springer (252) publish part in, the final number, of 

 their Revision of the Paheocrinoidea. This consists of section 2, j)p. 

 139-334, and an index, pp. 303-334, which, I understand, was not pub- 

 lished in the Proceedings of the Academy of N^atural Science. Although 

 section 2 of part in was presented to the Academy in 1886, it was not 

 published until 1887. This completes the grand work in which is given 

 a thorough diagnosis of each genus with citation of the known species, 

 and full bibliographic references for the Paliiecrinoidea. 



Part III is devoted to the discussion of the classification and rela- 

 tions of the Brachiate Criuoids, and the conclusion of the generic de- 

 scriptions. The following new genera and species are described : 



Stenocrhnis (syn. Heterocrinus ill part), \}. 207, type " Heterocrinus hetcrodac- 



iyhis," Hall, 1843.

 Stemmatocrinus Trautacholdi, p. 256, pi. 9, f. 7, 8, Low. Carb., Tennessee. 



C. A. White (279) gives a review of this book. The same authors, 

 Wachsmuth and Springer (253), discuss the Summit plates in Blas- 

 toids, Criuoids, and Oystids. (This paper is reviewed by C. A. White, 

 281.) This paper consists of a review and criticism of the opinions of 

 Etheridge and Carpenter as expressed in the " Catalogue of the Blas- 

 toidea in the Geological department of the British Museum (Nat. 

 Hist.), with an account of the morpliology and systematic position of 

 the group, and a revision of the genera and species. By Robert Eth- 

 eridge and P. Herbert Carpenter. Quarto. Pages i-xvii, and 1-322,20 

 plates, London, 18S6." The part discussed is found, particularly, in 

 chapter iv, pages 66-74 inclusive. Messrs. Wachsmuth and Springer 

 have prepared plates which accompany the i)aper illustrating the ven- 

 tral aspects of species of the following genera: Splicer onites, Cyathocri- 

 nus, Stephanoermus, Raplocriniis, Caryocrinns,Jnglandoc7'inus, Talaroeri- 

 nus, Elcvcrimis. In another paper (255) the same authors discuss the 

 characters of Grotalncrimis, and in (254) the structure of the ventral 

 surface of Taxocrinns.
