 and P. granulatus, Actceodes Ruppelii. Among those of the Isle of

 occur in the Torrid region), Atergatis sinuatifrons, A. and W., Car-

The Abyssinian province in its Red Sea portion contains seven 

 species of Atergatis, of which A. scidptus, A. exsculptus, and A. Savignii 

 are not elsewhere reported. Lambrus pelagicus, Actcea asper, Bup- 

 pellia tenax?, Thalamita chaptalis, are other species, besides many that 

 are common in the East Indies. Dromia unidentata is found in both 

 the northern and southern parts.

 lowing genera : — Egeria, Doclea, Micippa, Tiarinia, Mencethius, Lambrus, 

 Parthenope, Ceratocarcinus, Cryptopodia, Tlos, Atergatis, Carpiliw,

 of XanthidaB and Lupines are abundantly represented in the Liukiuan 

 province, so also the Galappino3, Seyllaridm, Sesarminm, Palinuridm, 

 and Squillidce. Eriocheir penecillatus, Ourtonotus longimanus, Trichia
