external influences. In these varieties Mr. Durrand's gatherings 

 are very rich, and it has been deemed more interesting to figure 

 some of these, rather than to give a hackneyed illustration of the 

 typical form. 



Fig. 2 with the flat base is closely allied to L. crenata, whilst 

 fig. 3 is flask-shaped and apiculate, with the delicate strife character- 

 istic of L. striata. This form has been figured by Reuss under the 

 name of L. strumosa* by Joseph Wright as L. semilineata, and by 

 Terquem as L. semiornata.

This species is well represented, being found in considerable 

 abundance at nearly all the Stations. 



Besides the typical oval form, specimens are frequent in which 

 the body is elongate and cylindrical, as in Phialina cylindracea 

 Seguenza,t or club-shaped as in L. grinzingensis Karrer.j: Others 

 are apiculate ; whilst many have the strise produced at the aboral 

 end, forming a brush of projecting spines. The striae are sometimes 

 continuous, in other examples interrupted or branching, and are of 

 various degrees of fineness, passing insensibly into L. sulcata.

This pretty little variety, as represented by the Malay Archi- 

 pelago specimens, is a form of L. striata in which the strias are 

 arranged spirally in place of longitudinally. It bears the same 

 relation to L. striata as L. spiralis bears to L. striatopunctata. 



It is abundant at Station 25 and occurs sparingly at a few other 

 Stations in both Areas. There is little or no variation in the speci-
