Description of a new species and variety 'found at Schull, Co. Cork, Ireland ; 

 a form intermediate between A. Insitanicits, Mab. , and A. stihfiisciis, Drap. 



A. fiagellns, sp. nov. "The slug alive measured 50 mm. in length, in alcohol 

 42 mm., with a mautle 13 mm. long. The head is of a bluish-white colour, which 

 gradually darkens or becomes a greyish blue on the tentacles. In the median line 

 of the body a broad, dark, Vandyke-brown coloured band extends from the 

 caudal gland to the mantle, and becomes less distinct after passing over about 

 half the length of the mantle. On either side of the body a narrower light-brown 

 band borders the median one, and this in turn is bounded by another Vandyke- 

 brown band about half the breadth of the median one. The sides of the body and 

 the foot fringe are of a light brownish white, the latter being striped with faint 

 sepia lines. The sole is pale yellow. The rugae are somewhat oval and fiat, 

 separated by deep sulci. The caudal gland is small and inconspicuous.'" 



The principal anatomical characteristics are, the constricted form of the free 

 oviduct and a small flagcllum at a point where the retractor muscle is attached to 

 the free oviduct. The oviduct and prostate are much convoluted and have 

 a position different from other species. Other points of difference are noticeable in 

 the hermaphrodite gland and in the alimentary, muscular, and nervous systems. 



Var. now. phillipsi. "Whole of the back and mantle of a deep mahogany- 

 brown colour and the sides of the body white with black dashes."

 Inst., 1S92, pp. 156-62. 



The Janellida, as the author remarks, are a most interesting order, and one 

 " w^hose extent, distribution, and classification appear to be but little known." 

 Combining, as Mr. Hedley does, the systematist and anatomist in one, we note 

 with much satisfaction the following remarks : — " Classification based upon 

 a single feature has never proved to be natural — that is to say, has never arranged 

 its subjects in the order of their blood-relationship. A classification to be natural 

 should l)e founded upon the aggregate characters, and the arrangement of the 

 pulmonate Gasteropoda by their jaws must be discarded, to share the fate of every 

 such system since the days of Linne." 



There are fourteen valid species enumerated, viz. : — /. hileutaciilata, (^. and G., 

 1832 ; _/. 7?iar??iorea, Hutton, 1879 ; Aneitella virs;ata, E. A. Sm., 1884 ; Aneitca 

 niacdonaldi. Gray, i860; A. graffei, Humbert, 1863 ; A. hiriido, Fischer, 1868; 

 A. modesta, Cr. and F., 1870 ; Hyaliinax perluiidiis, (^. and G., 1832 ; H. 

 viaiiritianus, Raug. , 1827 ; H. luatllardi, Fischer, 1867 ; H. reinhardti, Morch, 

 1872 ; H. viridis, Theob., 1864 ; H. andanianiciis, G.-A., 1882, and Farniarion 

 kersteini, V. Mts. , 1867. The following are mentioned as doubtful :—/■ vernicosa, 

 V. Mts., 1889, prol)al)ly identical with/, biteutaadata v. papillata, Hutt., 1879; 

 /. ntannoraia, \ . Mts., 1889, perhaps synonymous with_/. rnari/tona, Hutt. ; and
