Of terrestrial Mollusca we enumerate the following Limacidæ--_Arion ater_, _A. hortensis_, _Limax marginatus_, _L. flavus_, _L. agrestis_, _L. arborum_, _L. maximus_, and as before said one of the Testacellidæ viz., _T. Haliotidea_. Among the Helicidæ of course the common kinds are all present. Of the genus Zonites we have the following species: _Zonites cellarius_, _Z. glaber_, _Z. alliarius_, and its var. _viridula_, _Z. nitidulus_, _Z. purus_, and its var. _margaritacea_, _Z. radiatulus_, _Z. nitidus_, _Z. excavatus_ (one only, at Knowle), _Z. crystallinus_. Among the smaller species of Helix, attention may be called to the following: _H. aculeata_, a minute spiny coronet; _H. pygmæa_, the smallest of known Helices; _Helix fusca_, taken in two localities only, at Knowle and Selly Oak. Of the four species of Pupa found in Britain, two only occur, _Pupa umbilicata_ and _P. marginata_. Of the latter species a colony of the white variety has been found inhabiting a wall at Cleeve Prior, Worcestershire. Only two out of our eleven species of Vertigo have occurred, viz.: _Vertigo edentula_ and its variety _columella_, and _V. pygmæa_. Two Clausiliæ are found, _Clausilia laminata_ and _C. rugosa_. It is somewhat singular that of the four species inhabiting this country the last named is ubiquitous, while _C. Rolphii_ and _C. biplicata_ are local. The writer has taken the rare albino form of _C. rugosa_, at Selly Oak. That exquisite shell, _Cochlicopa tridens_, var. _crystallina_, has been taken in three places; the type is largely distributed in our neighbourhood, whereas in others it is rare, while _C. lubrica_ is widespread in England. _Achatina acicula_, dead shells only, Dudley Castle. _Carychium minimum_ is commonly distributed. In giving this outline of the Molluscan Fauna of our neighbourhood, the writer has called attention to the valuable papers on Embryology by Professor E. Ray Lankester, as shedding great light on the affinities of the Mollusca with other groups. CHAPTER IV. Insects. BY W. G. BLATCH.
