230 Records of the Indmn Museum. [Vol. IX , 



Scalp ellum alatum, Gruvel, Rep. ' Travailleur ' et ' Talisman,' 

 Cirrhipedes, p. 57 (1902). 



Specimens from ' Investigator ' station 232 : 7°i7'3o" N., 76° 

 54'3o" E. (430 fathoms) and o^thers from Indian seas labelled simply 

 " deep sea" agree in every respect with examples from off the 

 south-west of Ireland that I have recently examined. 



The spines on the degenerate male (see Hoek's fig. 10* on 

 plate IX in the first part of his ' Challenger ' report) have a very 

 characteristic form, but the whole specimen of that sex figured 

 under the name 5. eximium on the same plate was certainly 

 distorted. 



5. velutinum is one of the most widely distributed of the deep- 

 sea Cirripedia. It occurs on both sides of the N. Atlantic and off 

 Tristan d'Acunha; there are specimens in the British Museum 

 taken from a cable lying in 1200 fathoms in Lat. I2°20' N., Long. 

 52°3o' E. 



The bathymetric range is from 35 to over 1200 fathoms. As 

 Pilsbry points out, the species is closely related to 5. formae, 

 Alessandri, of the ItaUan Miocene. 



Type in the British Museum. 



3. Scalpellum trapezoideum, Hoek. 



Scalpellum trapezoideum, Hoek, Siboga-Expeditie, Mon.XXXIa 

 (Cirripedia Pedunculata), p. 102, pi. VIII, fig. 6 (1907); 

 Annandale, ///. Zool. 'Investigator,'' Crust. Ent., pi. IV, 

 fig. 9 (1908). 

 ? Scalpellum truncafum, Annandale in Herdman's Pearl Oyster 

 Fisheries (Roy. Soc. Lond.), part V, Suppl. XXXI, p. 142 

 (1906). 

 A specimen, dredged by the 'Investigator' at station 317 

 from 590 fathoms in the Gulf of Manaar (7°4' N., 79°32' E.) agrees 

 with Hoek's description and figures. It was identified by me as 

 (?) Scalpellum truncatum, Hoek, in Professor Herdman's report on 

 the Ceylon Pearl Fisheries, but clearly belongs to the species to 

 which it is assigned in the * Investigator ' Illustrations. It is 

 attached to a piece of coal. 



The species was originally described from Lat. 6°3o' S., Long. 

 I2°55' E. and from a depth of 2796 m. (=1508 fathoms). 

 Type in the Amsterdam Museum. 



4. Scalpellum pacificum, Pilsbry. 



Scalpellum pacificum, Pilsbry, Bull. Bur. Fish. U.S.A. No. 617, 



p. 182, pi. IV, figs. 3, 4 (1907). 

 Scalpellum tenue, Annandale {nee Hoek), Herdman's Pearl 



Oyster Fisheries, V, p. 142 (1906). 

 Cirri colourless, moderate. The anterior ramus of the first 

 cirrus flattened and expanded, especially in the 4th, 5th, and 6th 

 segments; the last (9th) segment much narrower than the others.
