234 J. MURRAY ON GASTROTRICHA. 



47. Parsons, F. A. In the Quekett Journal for 1896-7 there 



occur some records of Gastrotricha found at the excursions 

 of the Club. I do not know who made the actual iden- 

 tifications, but the records are referred to in Mr. Parsons's 

 name by various authors. 



48. Perrier, E. Traits de Zoologie, Fasc. 4, pp. 1534-9, figs. 



1103-5, 1897. 



A general account of six species, with some figures. 



49. Perty, M. Kleinste Lebensfovmen dev Schweiz, p. 47, 1852. 



A few remarks on the group and several known species. 



50. Pritchard, A. History of Infusoria, 1861. 



The earlier editions of Pritchard contain a few notes 

 after Ehrenberg. In 1861 there is a fair account of the 

 group.

K. Ges. Freunde d. Natuv., 50, 1886 (/. bogdanovii). 

 *52. Schmarda, L. K. Neue wivbellose Thieve, i. 2, 1861. 



Describes two new species as Ichthydium /. jamaicense 

 and /. tabulatum which are technically Chaetonotus, 

 according to his own generic definition of Ichthydium. 



53. Schrank, P. v. P. Beitvdge ficv Natuvgeschichte, 1776. 



His Bvacliionus pilosus (Part III., PI. 4, fig. 32) is, 

 according to Dujardin (16, p. 570, footnote), Chaetonotus 

 lav us. 



54. Ibid. Fauna Boica, hi., pp. 90-91, 1803. 



Tvichoda lavus ( = Bvacliionus pilosus), T. anas. 



55. Schultze, M. Ueber Chaetonotus mid Ichthydium Ehr. 



Avcli. f. Anat. u. Phys., vi., pp. 241-54. 



New genus Tuvbanella, which I believe is not a 

 Gastrotrich. 

 *56. Spencer. On a new Rotifer, Polyavthva fusifovmis. 



This is a Gastrotrich, since made the type of a new 

 genus, Stylochaeta, by Hlava (30). J. Q. M. C, 1890, p. 59. 

 *57. Stokes, A. C. Observations on Chaetonotus. The Micro- 

 scope (American), vol. 7, two parts, January and February, 

 1887, pp. 1-9, PI. 1 ; pp. 33-43, PI. 2. 



One of the most considerable works on the group, in 

 which a great many new species are described. They are 

 all regarded as Chaetonotus, the earlier generic distinctions 

 not being admitted.
