NOTES ON THE MADRAS 
M. victrix, the markings on the gastric region have arranged 
themselves in the form of three distinct circles. This variety 
(which may be designated var. annuUfera) apparently stands 
in the same relation to M. victrix, that M. circulifera, Miers,^ 
does to M. lunaris. 
2. Matuta lunaris (Herbst.). 
The smallest specimen examined has a length of carapace 
of 15 millim, the largest 36 millim. In all, the markings— 
which tend to form rings or short irregular lines — are more 
crowded on the anterior half of the carapace ; posteriorly 
they show a marked tendency towards the formation of a 
series of longitudinal lines. In young individuals the colour 
markings are evident, though much less abimdant, and the 
appearance of ring-like spots is well seen. The stridulating 
areas closely resemble those of M. vicfrix, with the exception 
that the oval one is usually composed of 4 — 5 ridges, and 
the linear of 8 — 10. In this species, as in the last, a beaded 
line is well seen on the outer surface of the movable finger of 
the male, but absent from the female. In the adult male, the 
outer surface of the hand is armed with two conical spines, 
the first short and triangular, the second more prominent ; 
from the latter a raised line is continued along the outer 
surface of the immobile finger. In the females and young 
males, the second spine is followed by two or thi'ee pyramidal 
tubercles which take the place of the aforementioned ridge. 
3. Matuta Miersii, ^ n. sp. 
Description. — Carapace finely granulated around the 
dorsal tubercles, and towards the lateral spines, elsewhere 
* Founded on a single specimen from the Malaysian Seas described and 
figured in Ann. Mag. Nat. Hist., Ser. 5, vol. 3, pi. XIV, fig. 5, p. 27 (sepa- 
rate copy), 1880. According to Dr. J. G. UeMan it is to be regarded aa 
a variety of il/. lunaris. 
' I have pleasure in associating this species with the name of my friend 
Mr. E. J. Miers, from whose revision of the genus I have received great 
assistance in the di'awing up of these notes.
