For the original definition of the genus Maera, see Note on Leach, 1813 (p. 84), 

 for that of Ceradocus, see Note on Costa, 1857 (p. 298), for that of Leptothoe, see Note 

 on Stimpson, 1854 (p. 277), and for that of Megamoera, see Note on Spence Bate, 1862 

 (p. 335). Boeck's definition of Meera is as follows : — 



" Mandibles with the third joint of the palp narrow, not very elongate. 



" First Maxillae with the inner plate narrow and aj)ically furnished with few 

 plumose setae. 



" Body elongate, narrow. 



" Side-plates little ; the fourth pair scarcely larger than the fifth. 



" Upper Antennae, much longer than the lower, the peduncle elongate. 



" The legs slender, elongate ; the Second Gnaihopods with the hand much larger 

 than in the first pair ; the Third, Fourth, and Fifth Perseopods with the first joint more 

 or less dilated. 



" The Third Uropods extended beyond the First and Second pairs ; the rami 

 elongate, narrow, very setose on the margin ; the inner ramus only a little shorter than 

 the outer. 



"The Telson not very elongate, deeply cleft." 



In Msera longimanus, Leach, the third joint of the mandibular palp is longer than 

 the second, and in Msera rubromacidata (Stimpson) the inner plate of the First 

 Maxillae has the plumose setse numerous instead of few, and not confined to the apex. 

 The epithet " few " should, I think, be omitted from the generic character of the First 

 Maxillae.
