(label bearing in pencil the words " A. acucinctus Spiti sbal[es]," 

 that were also transferred from the same Museum, but there is no 

 record whether they belonged to the Strachey Collection or not. 

 Amongst the specimens that undoubtedly belonged to the Strachey 

 Collection there is no single specimen from which all the figures la-c 

 on pi. xviii could have been drawn. Allowance must, however, 

 be made for the illustrations, for in his description of the species 

 Blanford says "The figure of this species given in plate 18 is, 

 in some respects, erroneous. The ribs in fig. la should conform 

 to the shape of the mouth, instead of being but slightly flexuous, 

 and the periphery should be ornamented with minute sharp teeth, 

 instead of crenulations." 



The specimen registered C. 7360a appears to be the original of 

 'fig. 16, the figure being reversed ; its size agrees also with fig. la, 

 but its sculpture is much less distinct, and its suture-line is not 

 visible. The sculpture of the species is best shown upon the 

 fragment registered C. 7360(i, and numbered in ink " 1840," which 

 at one time appears to have another piece attached to it ; this 

 fragment also exhibits traces of the suture-line, but these are quite 

 insufficient to have furnished the drawing of the suture-line given 

 by Blanford (fig. Ic). The form of the peristome indicated in 

 fig. la appears to have been drawn from the example No. C. 73606, 

 which is, however, only about one-half of the size of the figure. 

 The sculpture could not possibly have been taken from this specimen, 

 the surface of which is nearly smooth ; nor the suture-line, for although 

 feebly indicated it is not sufficiently preserved to have formed the 

 original of fig. \c. 



Of the two other examples of this species [C. 7361a, 6] which 

 were also transferred from the. Museum of Practical Geology, and 

 ■which most probably belonged to the Strachey Collection, although 

 direct evidence of this is wanting, one [C. 73616] exhibits the 

 suture-line very clearly, and there is every probability, not only that 

 these specimens originally formed part of the Strachey Collection, 

 but that the specimen C. 73616 furnished the original of the suture- 

 line represented in fig. \c} 



With regard to the figures of this species in the " Palaeontology 

 of Niti," I conclude, therefore, that fig. 16 has been drawn from the 

 specimen No. C 7360a ; tbat fig. la has been drawn in part from 

 the example No. C. 73606, and possibly in part also from the 

 specimens C 7360a and C. 7360d ; and that fig. Ic has been taken 

 from the specimen C. 73616. I have not been able to recognize 

 in the collection the original of figs. 4ia-d on pi. xix. 



The species was originally described by H. F. Blanford in 1863 

 r(Jaurn. Asiatic Society of Bengal, vol. xxxii, 1863, p. 126, pi. i, 

 figs. 3, 3a). He considered (p. 106) A. Lymani, A. Oppel (Pal. 

 Mittheil., iv (1863), p. 272, pi. Ixxvi, figs. 3a-c), to be a synonym. 



1 F. StoHczka (Mem. Geol. Surv. India, vol. v, pt. 1, 1865) says (p. 93), " Fig. Ic 

 in Strachey's Pal. pi. 18 gives no good idea of the true form of the lobes and 

 sadiiles. The figure was evidently taken from a specimen with a very much eroded 

 surface."
