has long been misapprehended, it generally being considered 

 to be a pupa. It was reserved to Dr. Von Moellendorff, in 

 Manila, to point out its true nature, and I am glad to say 

 that Mr. Pilsbry agrees with the opinion of Dr. Vozi Moellen- 

 dorff, and the writer. Having sent a small collection of New 

 Zealand shells to Manila, Dr. Von Moellendorff wrote to me, 

 under date 20th February, 1892 : " What do you think of Pupa 

 novoseelandica ? Boettger has elevated it to the type of the 

 sub-genus Tesseraria. I take it to be a Patulide, standing 

 nearest to Thera. Is the animal already known?" I never 

 fell in with a view more readily than with this. I had just 

 then published the description and figures of the dentition of 

 this species (Trans. N.Z. Inst., vol. xxiv., p. 300, pi. xxiii., 

 figs. 53, 54), and pointed out that the radula of this Pupa 

 differs considerably from all the others of the genus I have 

 seen. I wrote to Dr. Von Moellendorff that I fully agreed 

 with him, and, sending him a reprint of my paper, which con- 

 tains also the dentition of the two species of Thera, was able 

 to show him that his view was also borne out by the dentition. 

 With his next letter he kindly sent me a modified diagnosis of 

 Boettger's Tesseraria, of which I give here a copy : — 



" Tesseraria, Boettger, sec. Charopce. 



" T. pupaeforrnis, fere exacte cylindrata, apice obtuso, sub- 

 rotundato, costulata, rufo-fusca, maculis stramineis prsecipue 

 ad suturam tesselata. 



" Eadula et maxilla persimilis illis TJierce stipulates et 

 barbatulae, Reeve. 



"Type: Endodonta {Charopa) novoseelandica, Pfeiffer, 

 1854." 



Animal (fig. 17).— When living in the Forty-mile Bush 

 I made a sketch and short description of the animal, which I 

 think may be of interest now. 



The animal is nearly white, the eye-bearers greyish-black, 

 clavate, long (about 3mm.), the tentacles white, short 

 (about -Imm.), rounded in front. Mantle central; neck 

 with two blackish stripes running backwards from the eye- 

 bearers ; tail sharp above, slightly tapering, no caudal pore. 

 There is a distinct pedal line, to which run down the whole 

 length of the foot shallow diagonal grooves. Sole white, with 

 a slightly darker median disc, smooth all over. Length of 

 body 9mm., breadth of sole l^mm. 



15. Laoma leimonias, Gray, 1850. Plates XVI., fig. 18, and 



XVIL, fig. 19. 



No figure of the dentition of this mollusc has ever been 

 published, as it seems rather difficult to get a shell with the 

 animal. As it is the type of Laoma, Gray, it is most import-
