Indian Stalked Barnacles. 



It is convenient that lists of the Indian Fauna should be published in India, and I 

 have therefore ventured to print in these Memoirs a list consisting partly of names 

 which are, for the present, nomina nuda. This reproach, however, will, I hope, be 

 removed almost as soon as the present paper is issued, for I propose to diagnose the new 

 forms in the "Natural History Notes from the R.I.M.S. Ship 'Investigator'" {Ann. 

 Mag. N. H.) as soon as possible, and it is improbable that any of the descriptions will be 

 anticipated. The number of these new forms is due to the fact that extremely few 

 specimens from the seas of British India have hitherto been examined. This is especially 

 true of deep-sea forms. Indeed, so far as I know, only two species {Scalpellum squamuli- 

 ferum and Mega/asma carino-dentatum) have been recorded from a depth greater than, or 

 even approaching, ioo fathoms. Both of these were described by Weltner, 

 who found them attached to a sponge dredged by the " Investigator " and sent to Europe 

 for determination. Of the forms described by Hcek on the basis of " Challenger " mat- 

 erial, four (possibly five) occur in the " Investigator " collection, all belonging to the 

 genus Scalpellum. Of these, S. aculum was taken both in the Pacific and the Atlantic, so 

 that its occurrence in the Indian Ocean as well is not surprising ; 5. velutinum has been 

 dredged by various deep-sea expeditions at several points in the Atlantic between Portugal 

 and a station south of Africa ; 5. nova-zelandia was only known from off New Zealand, 

 and 6*. tenue from a point in the south of the Indian Ocean near the Croizets. 

 Note — In the following list, species whose names are distinguished by a * are not yet describ- 

 ed in print ; their diagnoses will be published as noted above. Those whose names are 

 indicated by a § are recorded in Gardner's Fauna and Geography of the Maldives and 

 Laccadives, Vol. I, by Borradaile. Descriptions of the remainder will be found in 

 Gruvel's recent Monographic dcs Cirrhipcdes (Paris, 1905.) I have omitted such 

 common and universally distributed species as Lepas anatifera and L. anserifera, the 

 latter of which is by far the most abundant form in the Indian Seas.
