41 The distinction of this species is its very uniform ornamental 

 In most of the Chitons there is some marked ditli-renee between the 

 lateral and central areas of the valves, but here all seems uniform in 

 the color as \\"11 as in the ornament. The lateral areas have con- 

 centric lines like those of growth. The minute dots with which the 

 surface is pitted is a feature which this species shares with many 

 others in Australia, but the marks are finer and more shallow than 

 usual. The species is very rare." ( Tenison- Woods.)

Chiton inomatus T.-W., Trans, and Proc. of the Roy. Soc. of 

 Victoria, xvii, p. 82, pi., figs. 8, 9 (May 10, 1881). Callochiton 

 (Stereochiton) lobatus CPR. 



The representation of the sutural laminae upon the posterior, 

 instead of the anterior border of the single valve illustrated in Mr. 

 Tenison- Wood's drawing, is of course on error; but it is difficult to 

 to see how such a mistake could occur. 



I believe that this species is the same as Callochiton ^Stereochiton) 

 lobatus Cpr. (Manual xiv, p. 53) ; and it is upon this ground that I 

 place the form in this genus and section. Teuison-Woods' descrip- 

 tion and figure give no clue to its generic position. C. lobatus Cpr. 

 becomes a synonym. 



CHITON FESTIVUS Blainville. Shell quite elongated, carinated ; 

 valves narrow, angular like a roof, very finely granulated through- 

 out ; lateral areas little indicated ; anterior plates of insertion 

 (suture laminae) narrow, the end plate quadridentate. Color varied 

 with brown, red and flesh color outside; white with a dash of 

 rose within. (Blainv. Diet. Sc. Nat. xxxvi, p. 541.) 



Seas of Australia. 



This is a Callochiton of the Section Trachyradsin, and may be 

 either C.fnlyetrum, Rv., C. castaneus Wood or inornatit* T.- Woods ; 

 The coloration described resembles the first of these. The locality 

 assigned is not to be trusted.
