Mr. E. A. Smith on Haliotis. 419 



Of T. fausta (typical) we possess six examples from the 

 Turco-Persian frontier, three from Kandahar, and one of 

 doubtful locality; the "Zeller" collection added seven 

 examples, in all of which the discocellular spot of primaries 

 is replaced by a minute pale-centred ring, and the pattern of 

 the underside is extremely pale ; these specimens were 

 received from Beirlit and Bagdad, and may either represent 

 a distinct local type or a seasonal form. Of T. faustina^ 

 owing to the generosity of Major Yerbury, we possess six 

 examples ; of T. orientalis the male type only ; of T. vi 

 eight specimens sent to us by Major Yerbury from Aden ; of 

 T. Solaris four males, for three of which we were indebted to 

 Col. Swinhoe ; of T. fulvia, previously unrepresented in our 

 series, we now have the male ; of T. trinotatus we have three 

 males and a female; and, lastly, we now have a pair of T. 

 PalUseri. Every species of this group hitherto described is 

 therefore represented. 



Of the carmine-tipped group Mr. Palliser obtained two 

 species, which he tells me are indiscriminately called T. 

 danae in Bombay : one of these, which was represented only 

 by a single male, is apparently a dwarfed example of that 

 species ; the other, of which there was a good series, is T. san- 

 ginnah's, and only differs from the Ceylonese types in being 

 slightly larger. 



Of the T. etricla group there were examples of T. himhura 

 and T. pernotatus^ the latter less heavily bordered than usual ; 

 and of the T. evanthe group, T. 2Jseudevanthe and T. titea. 



LVII. — Notice of an Ahnormal Orowth in a Species of 

 Haliotis. By Edgar A. Smith. 



The British Museum has recently acquired a specimen of 

 Haliotis which is remarkable for having two rows of perfora- 

 tions in the shell instead of one. So far as I can ascertain 

 this is the only instance recorded of such an abnormality. 

 The shell in question is an example of the large Japanese 

 species H. gigantea, and measures 5^ inches in length and 

 nearly 4^ in width. It is well known that the perforations 

 in the shells of Haliotis are caused by a slit in the mantle of 

 the animal at the particular part immediately beneath them. 

 Instead of perfecting the contour of the shell, in the course of 

 growth an interruption or sinus in the margin is produced,
