NO. 1671. \EW -S'LLG'.S OF GENUS rEROXICELLA—COCKERELL. 333 



anatomy of V. (jihon} is unknown. The following table of Pacific 



Veronieelhi' will assist in the separation of the species: 



Dorsuiu with a very distiiK-t light yellow band; female orifice close to sole; 



accessory glands 12 to 20 T'. wiUeyi Collinge. 



Dorsnni withont a hand, or with at most traces of one, not lighter than the 



ground color 1. 



1. Ground color dirty yellow, with small blackish blotches — V. gilsoni Collinge. 

 Ground color dark coffee brown 2. 



2. Form ^ery broad, the l)readth about half the length (according to the figure) 



V. hrunnea Collinge. 

 (Evidently based on a juvenile.) 

 Form narrower, the breadth less than half the length; accessory glands 8 



V. agassizi Cockerell. 



Our largest T". agassizi is 36 mm. long- and 14 mm. broad, the sole 

 3.5 mm. broad and the female orifice 3 mm. from sole and 23 mm. 

 from anterior end. The average measurements were: Length, 25.6 

 mm.; breadth, 11.6; breadth of sole, 2.7; female orifice from sole, 2.1; 

 female orifice from margin, 2.8, and from anterior end, 14.8. -The 

 female orifice is distant from the head 56.4 per cent of the total length. 



The jaw is normal, strongly ribbed, as is sufficiently shown in 

 fig. 1. The teeth are normal for the genus, with blunt dark points. 

 The median tooth is small and narrow, the cusp not projecting be- 

 yond the basal plate. The first laterals are large and simple in form 

 (fig. 4). The marginal teeth, as usual, are much smaller than the 

 laterals. 



The male generative organs are normal for the genus. The acces- 

 sory glands are strikingly different from those of T^. willeyi^ being 

 much shorter (little more than half the length of the dart-sac) and 

 fewer in number (eight in the specimen examined). In V. willeyi 

 they are not only numerous, but conspicuously longer than the dart- 

 sac. The intestine is formed essentially as in T".* ivilleyi and F. 

 brumiea, but the stomach is covered by the liver. (See fig. 3.) 



VERONICELLA SCHIVELYiE BAHAMENSIS Dall. 



This form Avas described by Doctor Dall ° from Nassau and Little 

 Abaco, Bahamas. The typical F. schivelyw Pilsbry comes from Ber- 

 muda and is exceedingly similar to the Mexican T'. morelett Crosse 

 and Fischer. Upon comparing the descriptions of T^. moreleti and 

 scJiivelyoE (external characters) , nothing distinctive was found, except 

 that the female orifice was slightly more posterior in schivelya\ and 

 the dorsal bands were rather nearer to each other than either to the 

 edge of the body. In the hahamensis form the bands are moi-e or less 

 evanescent in the adult though well-marked in the young. In all 

 a strongly distinctive feature is the projection of the foot be3'ond the 

 body posteriorly.
