The remarks made on L. striata apply equally to this form. The 

 ■variety interrupta is Jess abundant and less widely distributed.

This form, which elsewhere is somewhat rare, in the Malay 

 Archipelago is very abundant at some Stations in Area 2, especially 

 at No. 30 ; it is also found sparingly in Area 1. 



The great majority of the specimens are of the cylindrical variety 

 figured by Dr. Egger. In this form the ribs are broader than in the 

 flask-shaped variety, and are flattened or even hollowed on the 

 upper face. There is a rare variety in which the perforated alternate 

 with solid ribs, as in the specimens of L. desmophora from the 

 ' Challenger ' Expedition figured by Brady.* Both the cylindrical and 

 the flask-shaped forms are subject to an obliquity of the ribs, which 

 connects them with L. spiralis. Frequently the neck is inclined to 

 one side, as shown in the figured specimen. 



The sole ' Gazelle ' Station is Mauritius.

The first notice of this beautiful little form appears to be that of 

 Parker and Jones in 1865, when, in treating of L. striatopunctata, f 

 they write " The ribs are comparatively strong ; they range in number 

 from four to twelve, and in one recent specimen we have seen them 

 spiral." In 1871 it was figured by M. Ponton^ but was not described 

 by him. Brady's diagnosis of the species was made from an imperfect
