Specimen (c). 



On another 'card is a specimen, which I am calling (c)y 

 marked ' ' Liolophura hirtosa, Peron ; collected by Peron et 

 Lesueur, 1803." In Dr. Lamy's opinion this specimen is the 

 black variety described by Blainville, 1825, as variety V. of 

 his Chiton gemmatus. The shell shows very little sculpture, 

 the dorsal area is eroded, but the rest of the shell is well pre- 

 served. There are very deep growth-lines and ridges, which 

 are only subpustulose in the lateral areas. It is curled and 

 measures 30x23 mm. This sipm.. = Liolnphura hirtosa, 

 (Peron) Blainville. 



JVote. — Blainville states that his variety V. was in the 

 collection of the Paris Museum, but that the type of normal 

 C geinmatvs was in his own collection. 



Specimen card. 



This has two specimens mounted on it; they are marked 

 "Z. georgiana, Q. et G., Port du Roi George." These are 

 not that species, but are the Sydney shell L. gaimardi, Blain- 

 ville. Tliere are sufficient of the girdle spicules left to assure 

 the correctness of the determination. 



Specimen (e). 



This is in spirit and marked " Acanthopleura quatre- 

 fctgesi, Rochebrune (Rochebr., Bull. Soc. Philom., 1880-81, 

 p. 117; Jour, de Conch., 1881, p. 44)." This is Liolophura 

 hirtosa y (Peron) Blainville, and very probably was one of 

 Blainville' s original shells. 



Liolophura (Chiton) georgimia^ Quoy et Gaimard. Type 

 (Voy. de I'Astrol. ZooL, m.,'p. 379, t. 75, f. 25-30, 1833), 

 Port du Roi George. There are four specimens quite typical 

 of this common Western Australian shell; as Peron'e name, 

 hirtosus, was published by Blainville in 1825, that name 

 replaces that of Quoy et Gaimard. There are old labels 

 attached reading, ''Chiton magellanicus, Chem. ; Chiton 

 georgianus, Q. et G. Type figured. Port du Roi George, 

 New Holland, Expedition d'Urville, 1824, the figure in Voy. 

 Astrol., pi. 75, figs. 25-30, agrees with these specimens." 



Liolophura (Chiton) gaimardi, Blainville (Diet. Sci. Nat., 

 xxxvi., p. 546, 1825). Tlie type was collected at Port Jackson 

 by Quoy and Gaimard and was preserved in spirit. This 

 bottle contains two specimens with a more recent label, 

 '' Acanthopleiira magellanica, Chem." These may be the types, 

 as the type is referred to as being in the Paris Museum in the 

 catalogue of that Museum, dated 1838.
