GOPON. 



ANOMALPNA, D'Orb. With some ex- 

 ceptions (as An. elegans, D'Orb., which is a 

 small Discorbina} the Anomalince are some- 

 what biconvex TruncaiuUna, neat, discoidal, 

 and subnautiloid, with nearly as much con- 

 vexity of the chambers on the lower as on 

 the upper side of the shell. Abundant, both 

 recent and fossil.

ANOMALO'CERA, Temp. A genus of 

 Entomostraca, of the order Copepoda and 

 family Diaptomidoe. 



Char. Head distinguishable from the 

 body, with a bifid beak and a hooked spine 

 at the base on each side ; thorax with six, 

 abdomen with four segments; foot-jaws 

 three pairs ; last pair of legs differing from 

 the others ; eyes single, pedunculated in the 

 male ; right superior antenna with a swollen 

 hinge-joint (in the male); inferior antennae 

 not branched, three-jointed, basal joint with 

 a slender twig. 1 species :

AN'OPHRYS, Cohn. A genus of Holo- 

 trichous Infusoria, 



Char. Eree swimming, elongate-ovate, 

 pointed and curved in front, rounded 

 behind; a fascicle of longer and stouter 

 cilia issuing from the ventral oral cleft. 



A. sarcophaga (PI. 53. fig. 6). In salt 

 water, with decaying animal matter.

 ANOPLOPH'ORA, Stein (Opaline-pi.'). 

 A genus of Holotrichous Infusoria. 



Char. Body elongate or ovate, nucleus 

 band-like, axial ; contractile vesicles evi- 

 dent. 



The (15) species are intestinal parasites 

 of No-is, Lumbricns, and other Invertebrata.

 ANOPLU'RA. An order of Insects; 

 sometimes termed Parasitica or Epizoa. 



Char. Legs six ; wings none ; parasitic, 

 and not undergoing metamorphosis ; eyes 

 two, simple, or none. 



These insects are parasitic upon mammals 

 and birds, and are commonly known as lice. 

 The order is thus subdivided : 

 Subord. HAUSTELLATA (RHYNCHOTA). 

 Mouth with a tubular, very short 

 fleshy haustellum. 



Fam. PEDICULIDJE. Antennae five- 

 jointed. 

 Gen. Phthirius. Anterior legs for 



walking, posterior for climbing. 

 Pediculus. Legs all for climbing ; 



abdomen of seven segments. 

 Pedicinus. As Pediculvs, but abdomen 



of nine segments. 



Hcrmatopinm. Legs all for climbing ; 

 abdomen of eight or nine segments. 

 Hcematomyzus. Claws single. 

 Subord. MANDIBULATA (MALLOPHAGA). 



Mouth with two horny mandibles. 

 Fam. PHILOPTEBLDJE. Antennae fili- 

 form, maxillary palpi none. 

 Philopterus. Antennae five-jointed ; 



tarsi two-jointed, claws two. 

 Trichodcctes. Antennas three-jointed ; 



tarsi two-jointed, with one claw. 

 Fam. LIOTHEID^E. Antennas clavate ; 



maxillary palpi conspicuous. 

 Liotheum. Tarsi two-jointed, with two 



claws. 

 Gyropus. Tarsi two-jointed, with one 



claw. 



It appears that although the Anoplura do 

 not undergo metamorphosis as in the more 

 perfect insects, consisting of larva, pupa and 

 imago, widely diflering from each other in 

 gener.nl appearance, habits, and functions, 

 yet a series of semitransformations takes 

 place in the shedding of the skin a definite 

 number of times, by which the individual 

 acquires a greater symmetry of form, and 

 most probably a greater perfection of parts 

 or organs.
