120 G. C, Crick — Strachei/fi Cephalopoda from Himalaya. 



[Nos. C. 5050 and C. 5046]. They were regarded as of Jurassic age, 

 but they are much more probably Triassic fossils, and have been 

 elsewhere described as such by the present writer.^

(H. F. Blanford, in J. W. Salter & H. F. Blanford : Palieont. Niti, 1865, p. 86, 

 pi. XX, figs, la-c.) 



This species was founded upon a single specimen, which, as 

 described by Professor Blanford, " is an imperfect shell, and bears 

 the remains of three-fourths of another whorl. The figure is three- 

 fourths of the real size of the specimen." This fossil is now in the 

 British Museum collection [No. C 5038] ; it was transferred from 

 the Museum of Practical Geology, labelled with one of that 

 Museum's labels " Oolitic : Niti Pass. Ammonites Griffithi. Coll. 

 by Col. Strachey." The specimen is entirely septate ; the suture- 

 line (fig. \c) seems to have been taken from quite close to the 

 anterior end of the fossil, where it has been traced in white paint. 



According to Blanford (p. 106) this species is a synonym of 

 A. Theodorii, Oppel,^ a name which claims priority of publication. 



18. Ammonites strigilis, H. F. Blanford. 



(H. F. Blanford, in J. W. Salter & 11. F. Blanford: Paloeont. Xiti, 1865, p. 87.) 



Professor Blanford refers to an example in the Strachey Collection 

 in the following terms: — "A single specimen (cut in lialf and 

 polished) of this Ammonite (without specified locality) only dift'ers 

 from the original Spiti specimen in its somewhat larger size. 

 Diameter of shell, 2^ in. Diameter of outer whorl, li in." 



I have not been able to identify an examjtle of this species in 

 the Strachey Collection in the British Museum, but the National 

 collection contains tlie specimen [39,797], to which, when describing 

 this species in 1863 (Journ. Asiatic Soc. Bengal, vol. xxxii, 1863, 

 p. 126) from the half of a cut specimen, Blanford refers as possibly 

 the fellow of the type-specimen. It is labelled •' Himalaya"; but 

 its history and exact locality are unrecorded. 



19. Ammonites acucinctus (R. Strachey MS.), H. F. Blanford. 



(H. F. Blanford, in J. W. Salter & H. F. Blanford: Palasont. Niti, 1865, p. 87, 

 pi. xviii, figs, la-c ; pi. xix, figs, ia-d ; var. a(A. mimdHs, R. Strachey MS.), 

 pi. xviii, figs. 2a, b.) 



Of this species the British Museum collection contains five more 

 or less incomplete examples [Nos. C. 7360a-e] that belonged to 

 the Strachey Collection and were transferred from the Museum of 

 Practical Geolojjy, labelled with one of that Museum's labels 

 "Oolitic: Niti Pass. Ammojiites acucinctus (Stra.). Coll. by Col. 

 Strachey " ; also two other examples [Nos. C 7361a, 6], with a plain
