igoç.] N. Annandale : The Indian Cirripedia Pedunculata. yy 



L. anserifera ; not so broad at the base as long ; internal umbonal tooth on the left 

 scutum only; a prominent external basal ridge on both. Carina usually pectinate 

 dorsally, otherwise as in L. anserifera. 



Peduncle shorter than capitulum, somewhat compressed, bearing a distinct 

 pale vertical ridge on the occludent surface and two similar parallel ridges on the 

 dorsal surface, variable in colour, generally deep purple slightly paler both at the 

 base and the apex. 



Lining membrane of the capitulum deep purple, not changing to orange on the 

 sides of the aperture. Body Hlac-purple; first, fifth and sixth cirri dark purple, the 

 two latter brownish at the base; other cirri yellowish, with the anterior and posterior 

 surfaces purple; anal appendages brown ; mouth parts coloured as m L. anserifera ; 

 lateral appendages white. 



Cirri, etc. — Cirri much as in L. anserifera. Penis likewise. Lateral appendages 

 only two on each side, one on the prosoma, the other at the base of the first cirrus, the 

 latter being very long and delicate. Anal appendages as in L. anserifera. 



Mouth PARTS much like those of L. anserifera, but the inner angle of the mandible 

 is more slender and has a much stouter fringe of bristles on the lower than on the 

 upper margin. 



Closely as this form appears to resemble some specimens of L. anserifera exter- 

 nally {of. Pilsbry, Bull. U. S. Nat. Mus., No. 60, pi. viii, fig. 3) I assign it to L. anati- 

 fera, mainly on the ground of the characters exhibited by its lateral appendages. It 

 agrees as regards the markings on its terga and scuta with Darwin's var. A of the latter 

 species, but differs in other respects, notably as regards the ridges on the peduncle, 

 which seem to be a constant and characteristic feature. How far it is identical with 

 the specimens in Prof. Herdman's collection from Ceylon I am not now in a position 

 to say, as I only reserved one of these specimens, and that one an example in a bad 

 state of preservation. At the time I examined Professor Herdman's collections, 

 moreover, I had not had the same experience as regards the I^epadidse as that which 

 the examination of large numbers of specimens has since given me. 



Subgenus Dosima, Gray. 



The only species of this subgenus as yet known [L. fascicularis, lîllis and Solan- 

 der) has not yet been taken in Indian seas but was obtained by the " Siboga ' ' in the 

 Malay Archipelago (whence it was also recorded by Darwin) , and therefore may occur 

 in our waters also. There are no Oriental specimens in the collection. I quote Dar- 

 win's description for convenience of reference : — 



''Valves smooth, thin, transparent; carina rectangularly bent, with the lower 

 part expanded into a flat oblong disk. Filaments five on each side ; segments 

 of the three posterior cirri with triangular brushes of spines." 



The peduncle is often surrounded by a globular mass of dead vesicular substance, 

 and several individuals are not infrequently joined together by means of a mass of 

 the kind secreted by them in common.
