Bethel recently found a Veronicella, which he brought to me alive. Among the species re- corded from Mexico and Central America, it closely resembles only V. mexicana (Pfeffer), which occurs at Vera Cruz. It appears to be distinguished by the broad sole, and female orifice well caudad of the middle and very close to the sole. Internally, the accessory glands are numerous and very long. On the whole, however, it is so close to V. mexicana that I record it as a its status will variety ; only be precisely determined when more material is available for compar- ison. It is not that V. mexicana was impossible composite ; certainly the example sent by Strebel to Semper seems doubtfully identical with the animal figured in Strebel's work on the Molluscaof Mexico. One species of Veronice/la, V. stolli von Martens, has already been described from Guatemala. Its anatomy is unknown, but it is read- ily known from Mr. Bethel's slug by the presence of a narrow median longitudinal yellow band. It may be that V. stolli is iden- tical with V. olivacea Stearns from Nicaragua. An unnamed Veron- icella from Honduras, briefly described in NAUTILUS, April, 1895, p. 142, seems on the whole intermediate between our slug and V- mexicana. It is most probably conspecific with our animal, but it may represent a different, allied, species. Its anatomy i. -inknown. Z THE NAUTILUS. Veronicella mexicana betheli v. nov. Above, warm red-brown, paler toward the sides, with scattered dots dorsal and subdorsal pale ; regions irregularly and not densely with blackish the anterior third this speckled ; on speckling is re- solved into a pair of obscure bands, a little nearer to each other than either to the lateral margin. Beneath pale reddish, darker poster- iorly, and speckled with pale. Sole pale ochreous. Tentacles dark grey. There is not the slightest indication of a pale dorsal line. Under a lens, it is seen that the body above and below (especially posteriorly below) is very closely beset with minute pale dots, which correspond with punctiform depressions, while over this pattern are set numerous much larger diffused pale spots.
