THE NAUTILUS. 41 
Myllita inequalis n. sp. 
Shell obovate, very inequilateral, equivalve, solid whitish, with 
moderately convex valves, the beaks at about the posterior third, 
not prominent; sculpture of concentric punctate striz and, toward 
the ends of the shell, feeble radial ribs not prolonged to the medial 
part of the disk from which they appear to divaricate; hinge as in 
the M. Deshayesii except that the cardinal tooth is petaloid rather 
than /\-shaped ; posterior laterals short; the pallial line somewhat 
sinuous or impressed anteriorly, ventral margins of the valves plain. 
Lon. 3, alt. 2°4, diam. 1:7 mm. 
This was received from South Australia where it was collected by 
E. H. Matthews, Esq. It is immediately separable from any of the 
other species of Myllita by its form and inequilateral, feebly sculpt- 
ured valves. 
The shell of M. tasmanica contained the dried animal and a 
multitude of minute young fry included in the parental tissues. The 
dry foot was ligulate with a very large byssal sulcus. 
The hinge of Myllita seems quite close in its essential features to 
that of Lasea rubra. 
NOTE ON ISCHNOCHITON ONISCUS Krauss AND I. ELIZA- 
BETHENSIS Pilsbry. 
BY, E.R. SYKESgeBe Ay. Bo. 8. 
In a paper by Mr. Pilsbry’ specimens previously recorded from 
South Africa under the name of ‘ Chiton marginatus’ were described 
as a new species under the name of IJschnochiton Elizabethensis. 
About the same date I expressed’ the opinion that these specimens 
should really be referred to J. oniseus. My paper was in type when 
Mr. Pilsbry’s appeared, but I was able to call attention to his views 
in a foot-note. 
Recently I have had submitted to me a series of specimens, care- 
fully preserved in spirit, and have come to the conclusion that Mr. 
Pilsbry was quite right in his separation of I. Elizabethensis, and 
that the species I now have from Durban, Isipingo, and Umkomaas
