length, instead of one fifth ; if the latter were the case, the shell would he an 

 extremely slender one, and comparing it with Gouldiana, as a shell of the 

 same type, I would prefer to consider Gould's figure as more probably correct, 

 than his measiirement. Now, allowing for these discrepancies in Gould's ori- 

 ginal statements, I am inclined to think that Pfeiffer's species is very closely 

 allied to, if not exactly identical with, true insignis, hut Hanley and Theo- 

 hald's figures certainly seem to he somewhat different from hoth the preced- 

 ing ; however, they do not exclude the possibility of representing mere 

 variations of one and the same species. Whether the form of the aperture in 

 Gould's original figure is slightly exaggerated or not, I think the great ex- 

 pansion of the outer lip is decidedly somewhat abnormal, and setting aside 

 this point the remaining differences between the shells figured as insignis 

 are not greater than those between the different varieties of loxostoma or 

 Gouldiana. 



In order to clear up the matter more easily I add here (fig 12«) a copy 

 of Pfeiffer's figure of insignis. I greatly regret that I have not got the oppor- 

 tunity of examining Mr. Theobald's two type specimens, figured in the 

 Conchologia Indica as ' insignis' and var. gracilior, but possibly I may be 

 in a position to supply the deficiency in the next number of the Journal. 



15. Cl. vespa. (Ad p. 205.) 



The shell delineated by Mr. Blanford as a variety of vespa may be con- 

 sidered as a fair representation of that species ; but I add a figure (15«) 

 and description of a specimen obtained by Mr. Theobald at Tavoy, whence 

 vespa was originally got, and which is undoubtedly Gould's species. 



(15«). Cl. testa ovato-cylindracea, ad apicem obtusiuscula, albida, medio 

 subinflata, ultimo anfractio sensim attenuata, haud rimata, fusco castanea ; 

 anfractibus sex, convexiusculis, sutura simplici junctis, transversim oblique et 

 confertissime striolatis ; apertura sicbovata, postice rotundate subangulata, 

 antice late sub-effusa, intus violaceo rufa, peritremate modice expanso, interno 

 oblique fere recto, libero, biplicato ; plica antica, vel wferiore,valde obliqua, 

 sub-immersa ; plicis palatalibus novem tenuibus, supera longissima, circiter 

 l - 2 m.m. a margine suturali distante, alteris brevioribus et inter se valde 

 inceqiialibus. 



Long. 24.6 m.m., lat. 7 ; long, apert. cum perist. 63, ejusdem lat. 4'8 m.m 



Although allied to JBliillippiana the present form is undoubtedly quite 

 distinct, differing from Pfeiffer's species by a more slender shape, smaller 

 aperture, free inner lip, peculiarly flattened or almost canaliculated aperture 

 on the anterior end, and by the larger number of palatal plicae.
