are thickly covered with hair. There is, according to Sars, 

 a possibility, which, however, S. I. Smith thinks an impro- 

 bability, that the species may be the same as one earlier 

 but all too briefly described by Stimpson, from the coast 

 of Florida, ander the name Scyra umbonoM. The speci- 

 men taken by the Porcupine was first described as Amathia 

 Carpenteri, but the genus Amathia, Roux, has a pre-occu- 

 pied name which has in consequence since been changed, 

 by S. I. Smith, to Anamathia, and Professor A. Milne- 

 Edwards discovered that the species Ca.rpenteri could not 

 be included in that genus. At the same time he noticed 

 its likeness to Stimpson's species above mentioned, and 

 framed for it the new genus Sciframailiia. From the fore- 

 going remarks it will easily be understood what suggested 

 the composition of this generic name, but it must not be 

 forgotten that Scyr amathia belongs to the family Maiidae, 

 whereas Anamathia stands in the previously described 

 Inachidae, and Sryra (though to the exclusion of Stimp- 

 son's species umhonata) is a genus belonging to the next 

 family, the Pericerid^e. 



Family 3 . — Periceridce. 



The eyes are retractile within the small circular and 

 well-defined orbits, which are not incomplete as in the 

 Maiida3. The basal joint of the second antennae is well 

 developed, and constitutes a great part of the inferior wall 

 of the orbit, the joint being in general much enlarged. 



The family contains about twenty genera. 



Pericera, Latreille, 1829, of which the type is Pericera 

 cornndo (Herbst), 1804, has been despoiled of many of 

 its species by Miers, who has transferred them to Macro- 

 ca^loma, a new genus which he instituted in 1879. Of 

 the species Maorocoiloma trispinosa (Latreille) Mr. Ives 

 says that Yucatan specimens when alive are of a bright 

 scarlet colour. In the Challenger species, Macrocceloma 

 concdva, ]\liers, from Bahia and Fernando Noronha, the 

 body and limbs are covered with a short close pubescence 

 and with some longer curled hairs. Its colour in spirit is
