HARGITT. 



Liriope sciitigcra McCr., but closer inspection will show that in 

 several respects it differs very materially. It would seem to be 

 much closer related to L. ccrassiforuiis. Specimens of various sizes 

 showed the various phases in the development and atrophy of the 

 secondary, interradial tentacles, so that in the adult there are only 

 the four perradial tentacles. They were taken in the surface tow 

 near the Gulf Stream. In size the adult specimens were about 10 

 mm. broad by slightly more than half this height. Bell very 

 transparent, gonads opaque, somewhat shield-shaded, and show- 

 ing ova in various stages of growth. The centripetal canals were 

 twelve in number, the interradial set being about twice the size of 

 the adradial set. It should be noted that these were exceedingly 

 difficult to distinguish on superficial examination, and this may 

 in part account for their apparent absence in the earlier figures of 

 L. scntigcra.

on two different occasions during the summer and apparently 

 entirely new to science. Several specimens were taken in the 

 same general locality between that above mentioned and the Gulf 

 Stream. In shape the bell is somewhat oblong, with an extended 

 apical projection. Gastric portion of the manubrium rather large 

 and subquadrate in cross section, mouth simple and with slightly 

 everted lobes ; gonads in four rather prominent masses surround-
