152 A HISTORY OF RECENT CRUSTACEA 
the trunk, a mistake which Professor Smith has now cor- 
rected. Remipes testudinarius, Latreille, has been recorded 
by this and various other names from many parts of the 
Indo-Pacific region. Its true name would seem to be 
Remipes adactylus (Fabricius). Remipes scutellatus (Fabri- 
cius) is found in the Atlantic. 
Mastigochirus, Miers, 1877, meaning ‘ with a whip-like 
hand,’ was previously called Mastigépus by Stimpson in 
1858, but the name being pre-occupied had to be changed. 
Its chief distinction from Hemipes rests on the form of the 
long and slender first pair of legs, which have the terminal 
joint subdivided. The type specimen of Mastigochirus 
guadrilobatus, Miers, came from the Philippine Islands. 
A comparison of this with others subsequently obtained by 
the Alert in the Prince of Wales’ Channel showed Mr. 
Miers that ‘the number of joints in the terminal flagelli- 
form portion of the anterior limbs (which are imperfectly 
seen on account of the hairs with which they are thickly 
clothed) was understated in the original description ; in- 
stead of being ten or twelve, they are usually twice as 
bumerous.’ 
Family 2.—Albuneide. 
The third maxillipeds are subpediform, with the fourth 
joint not greatly dilated; there is a small exopod. The 
first pair of legs are flattened and chelate. The telson is 
ovoid. 
Albunea, Fabricius, 1798, has for its type species the 
little Albunea symnista (Linn.), from eastern waters. The 
carapace is strongly grooved behind for the reception of 
the small first segment of the pleon. In Milne-Edwards’ 
‘ Histoire Naturelle des Crustacés,’ vol. 2, p. 202, the dis- 
tinguishing characters of Remipes and Albunea are trans- 
posed, but the error is subsequently corrected. 
Legion 2.—Inthodinea. 
The carapace is broadly ovate, uneven, with the regions 
well defined and a prominent rostrum. ‘The first antenne 
have cylindrical peduncles of moderate size and short
