The anatomy of Veronicella is given in Vol. I, Plate IV, of Terr. 

 i\Ioll. 



The contractility of the animal is very great. When extended it is 

 very long and slender and smooth or faintly reticulated, tliree or four 

 times as long as when contracted, in which latter state it has an oblong 

 form equally rounded at both ends, and its surface is coai-sely wrinkled, 

 granular, or tuberculated. The tentacles are generally bifurcate at tip, 

 or rather there is a supplementary tentacle or spur, which can be pro- 

 truded just short of the point of the tentacle; sometimes the tips are 

 said to be even palmate. In the plate the tentacles are simple (see be- 

 low, p. 440). 



It lives in families under stones and trunks of trees, and sometimes 

 buried in the earth. It is capable of retiring, from damp places, and 

 sometimes inhabits very dry localities. It issues forth in the night and 

 on wet days, when it maj' be found upon trees. Its movements are 

 very rapid ; .no slimy traces are left behind them, as in the case of the 

 Li))iaces. 



The eggs are large and oval, ten or fifteen being joined together in a 

 necklace-like, gelatinous thread, which is coiled and more or less covered 

 with mucus.

small, long and narrow, attenuated to a point above, gradually enlarg- 

 ing towards the base, above which are lateral, bluntly pointed, wing- 

 like expansions ; the lower margin is broad and has a deep, rounded 

 excavation ; in some cases the lateral expansions are so produced as to 

 give an almost cruciform appearance to the base of attachment; below 

 the center of the base of attachment, on its anterior surface, is a stout, 

 blunt, short, simple cusp, ending in a short, stout cutting point. The 

 lateral teeth are very irregular in shape, but retain the bicuspid char- 

 acter peculiar to the GeopMla ; they are longer and much wider than 

 the centrals ; the bases of attachment are very irregular in shape, very 

 asymmetrical, subquadrate or irregularly excavated above, thence curve 

 outwards and downwards, until at their lower extremity they exhibit
