ON THE BRACIIYUROUS DECAPODS OF THE CAPE. 
Stirps. CALAPPINA. 
Fam. MATUTIDAL 
Genus. MATUTINUS. 
Sub-genus. Matuta, Fab. 
Sp. 33. (Matutinus) Matuta Victor, Fab. 
Matuta victor, M. E. Hist. Nat. des Crust, vol. ii. p. 115. tab. 20. fig. 3 and 6. 
Note. I agree entirely with my lamented friend Dr. Leach in thinking, that there are many 
species confounded together under the name of Matuta victor. I do not consider the above 
names of the family and genus to possess any authority, and merely publish them in order that 
the reader may understand the relation which the sub-genus bears to the stirps Calappina. 
Stirps. LEUCOSINA. 
Here likewise I shall not pretend to characterize the families, or to describe the genera of a 
stirps in which so few species are as yet known; but shall merely content myself with the 
following description of the only sub-genus of the groupe which is known to be found at 
the Cape of Good Hope : — 
Sub-genus, Leucisca, M ( L. 
Body in front slender and compressed, but behind thick. 
Cephalothorax smooth, plane, depressed, sub-elliptical, broader than long, and having a thin 
reflexed margin; while the clypeus is advanced with a round sub-reflexed apex, which is 
scarcely emarginate. 
Orbits small, sub-circular, and hidden under the clypeus; while the eyes are deeply set, very 
minute and globose. 
Exterior Antennae very small and rather tri-articulate. 
Interior Antenna; hidden under the clypeus in transverse reniform fossulse. 
External Pedipalpi very large, and closing a triangular buccal cavity; their second joint is 
oblong, quadrate, and broader in front than the third, which is triangular, with a sharp 
point, while the external palpus is lunate. 
Feet; first, second, and third pairs have been lost in the only specimen before me; but the 
two remaining pair are short, and all are inserted under the margin of the cephalothorax. 
Abdomen of the female with four segments. 
The nearest crab to this is one from the Red Sea, which is described by Riippell under the 
name of Oreophorus horrulus. Both come near to Calappina. 
Sp. 34. ( ) Leucisca squalina, n. s. 
Descr. Leucisca alba, dorso medio convexiusculo, oculis glaucis, pedipalpis extends palpisque 
margine externo granulatis, pedibus articulo quarto extus sulcato, unguibus longis acutis. 
Note. The length of this curious little crab is only about three lines; and my specimen is 
much injured, having lost the chelae, and several other of the feet. The abdomen also is 
in a damaged state.
