64 G. C. Crick — Strachef/'s Cephalopoda fro)n Himalaya. 



Besides these seven specimens five fragments were also transferred 

 from the Museum of Practical Geology as part of the Strachey 

 Collection. They are accompanied by a Jermyn Street Museum 

 label bearing the inscription " Oolite : Niti Pass. Belemnites 

 sulcatus, var. canaliculatus. Stra. Him. PI. 10. Pres. by Col. 

 Strachey," and are now numbered C. 2565a-e. Only two of these 

 have any original ink-marks on them ; the specimen No. C. 2565c 

 is numbered " 1015," like the original of fig. 3, and the example 

 No, C. 2565fc is marked " Laptet." The "L" of the word Laptet 

 is in the same handwriting as, and precisely like, the " L " on the ' 

 specimen represented in fig. 6 [No. C. 2571]. It is therefore 

 possible that the " L " on that specimen may stand for " Laptet." 



On p. 106 of the " PaL^ontology of Niti," H. F. Blanford puts 

 Oppel's Belemnites Gernrdi as a synonym of the present species, 

 for which he retains Miller's name B. sulcatus, this claiming^ 

 priority of publication. 



With regard to the dimensions of the specimens Professor Blanford 

 says : " The largest specimen in Colonel Strachey's collection 

 measures as follows : — length, 3'6 in. ; antero-posterior diameter, 

 0*9 in.; transverse diameter, 0*9 in." There appears to be some 

 mistake here, because the largest guard at present in the collection, 

 the original of fig. 1, has the following dimensions : — length, 

 126*5 mm. (nearly 5 inches); antero-posterior diameter, 30 mm. 

 (1*2 in.) ; transverse diameter, 28 mm. (about I'l in.). The 

 specimen represented in fig. 2 is nearly of the same size, its 

 measurements being : — length, 115 mm. (4*5 in.) ; antero-posterior 

 diameter (at about 30 mm. from the anterior end), 27 mm. (1*05 in.) ; 

 transverse diameter (at same place), 27 mm. (1'05 in.). 



2. Ammonites alatus (R. Strachey MS.), H. F. Blanford. 



(H. F. Blanford, in J. W. Salter & H. F. Blanford: Pal^ont. Niti, 18C5, p. 76, 

 pi. xviii, iigs. 3«, b.) 



Of this species three fragments belonging to the Strachey 

 Collection are now in the British Museum. Two of these 

 [Nos. C. 7364rt and 6] are accompanied by a Jermyn Street 

 Museum label bearing the inscription "Oolitic. Niti Pass, Ammonites 

 alatus. Coll. by Col. Strachey," but they are not numbered in ink 

 like many of the Strachey specimens. With them there is a 

 guttapercha squeeze of the example numbered C. 7364a. To the 

 third specimen [No. C. 7365], which is numbered " 1834" in ink, 

 there is attached a label bearing the words " alatus. Spiti Shales " 

 written in pencil. 



One specimen [No. C. 7364t] is merely the impression of the 

 half of one side of a shell ; the other two [No. C. 7364a and 

 No, 7365] are evidently " the two fragmentary casts " from which 

 was "compiled " the "restoration " that is represented in Blanford's 

 pi. xviii, fig. 3n. There is no specimen in the collection which can 

 be identified with Blanford's fig. 36, the original of which possibly 

 furnished the dimensions given by the author.
