Description of three apparently new Species of Corn Crakes^ (Crex.) 
In the Collection of the British Museum. 
Red-neck Corn Crake. Crex ruficollis. Head, neck, chest, and upper 
part of back bright chestnut ; back, wing-coverts, and abdomen, black, 
white-streaked ; tail black, white spotted ; quills and secondaries plain 
brown, outer quill short, with a narrow white outer edge ; bill and feet 
brown. Bill to gape 6, to front 5, tarsus, 11 middle toe 14 lines. 
Length 6J inches. Inhab. Cape of Good Hope } 
Beautiful Corn Crake Crex pulchra. Head, neck, chest, upper 
part of back and tail bright chestnut-brown ; chin rather paler ; body- 
black, with small round, white spots above, and larger beneath, placed 
in pairs ; quills brown, white-spotted principally on the outer edge ; bill 
and feet brown. Bill to gape 8J, to front 7 ; tarsus 15 ; and middle 
toe 15 lines. Length 7 inches. 
Brown-eared Corn Crake. Crex aurita. Above olive-brown ; crown 
of head, front of neck, and beneath, bright chestnut; lores, orbits, and 
ears brown; bill rather thick, to gape 10, to front 9; tarsus 16J ; 
middle toe 18 lines. Length 7 inches. 
Description of a new Genus of Cirripides, allied to Balanus. In 
the British Museum. 
Gen. Elminius. Fam. Balanidce. 
Shell subcylindrical ; valves thin, solid, shelly, four, the front one 
narrow, involute, arched, overlapping the front edge of the wide lateral 
ones, (which occupy the width of the two lateral ones of the genus Bala- 
nus) the hinder one the narrowest, with a broad wing on the upper part 
of its sides, which are overlapped by tl^e hinder edges of the side valves ; 
operculum four valves ; valves articulated together, exactly closing the 
mouth ; qase membranaceous. This genus agrees with Balanus in shape, 
and with Coma in the number of its valves, but the valves are not porous 
as in that shell. 
King's Elminius. Elminius Kingii. Shell subcylindrical, truncated ; 
valves white, smoothish, covered with a pale brown periostraca, the front 
opercular valves, smooth, very obscurely grooved. 
In the Zoological Journal, ij. 210, Dr. Leach has established a genus 
under the above name, with the character Testa quadripartita solida, but 
the species which bears the name of Elminius petrosus in the British 
Museum, distinctly shews six valves, all so very closely soldered together 
as to be very difficult to divide ; under these circumstances I have adopted 
his generic name, as the character agrees with that of my shell, but the 
species for which he formed it must be referred to Balanus. 
Kote on a peculiar structure in the Head of an Agama. By EE. Gray. 
In a skull of an animal allied to Agama, or Uromastyx, in the College 
of Surgeons, I have observed that the Ramus ( Os. Complementaire, Cuv. 
Os. Fos. fig. c.) of the lower jaw rubs against the lateral processes of the
