spots at the base, anterior margin a little 

 convex and ciliated. Mandibles (f) slightly 

 curved, clothed with long hairs, notched 

 near the apex ; larger in the females, and but 

 slightly notched below the apex. Maxillce 

 ((/) with the basal portion short and broad, 

 hairy, the edge above pectinated, terminal 

 lobe* long and lanceolate, with a small pencil 

 of hairs at the apex. Palpi (h) rather long 

 and setaceous, 6-joiuted, basal joint short, 

 second long, the" remainder decreasing in 

 length. Mentum rather short and linear. 

 Tongue (*) very long and slender, ringed and 

 tubular, the interior margins very pilose, 

 terminated by a lanceolate appendage. Pa- 

 raglossce (of) lanceolate. Palpi (&) extend- 

 ing as far as the tongue, slender, tapering, 

 4-jointed, basal joint very long, second not 

 half the length, ciliated towards the apex, 

 third inserted below the apex, and very 

 small, as well as the fourth. Head sub- 

 trigonate ; eyes (c) long and narrow ; ocelli 

 (b) three. TThorax much broader than the 

 head in the female. Legs rather robust ; 

 tibiae, posterior dilated and very pilose ex- 

 ternally, and the intermediate ones also in 

 the females ; tarsi, intermediate pair long in 

 the males, the basal joint of the 4 posterior 

 dilated in both sexes, and furnished with a 

 strong brush at the apex in the hinder pair 

 of the female. Claws bifid in the males, 

 with a tooth on the underside in the female. 

 Pulvilli distinct. Male thickly and minutely 

 punctured, and clothed with fulvous or yel- 

 lowish hairs, more or less black at the apex 

 of the abdomen ; female black, very pilose.

AKTHOPHY'SA, Duj. A genus of In- 

 fusoria, of the family Monadina, Duj. ; Fla- 

 gellata, Kent. 



Char. Bodies ovoid or pyriform, with a 

 single anterior flagelliform filament (two, 

 one shorter than the other, Kent), and ag- 

 gregated at the ends of the branches of a sup- 

 port or polypidom, which is secreted by them. 

 The groups, when free, resemble Urella, 

 and revolve in the liquid containing them. 



The branched support is of an irregular 

 arborescent form, at first soft and glutinous, 

 afterwards becoming brownish, horny, and 

 nodular in appearance. According to Cohn, 

 the brownish filaments so frequently found 

 in decomposing pond- &c. water, are the 

 stalks of Anthophysa, and form Kiitzing's 

 genus Stereonema.

Body thicker in front j length of stalks 1-250

 Fig. 13 b represents a detached animal with

 Epistylis vegetans of Ehrenberg. The de- 

 tached groups of bodies form a species of

 common.

ANTIMONIATE of soda. The produc-

 niate of potash to a neutral or alkaline solu- 

 tion of a salt of soda, is used as a test of the 

 presence of soda. The crystals are repre- 

 sented in PL 10. fig. 21.

ANT'LIA. The spiral tongue or probos- 

 cis of the Lepidoptera. 



This well-known beautiful organ (PL 33. 

 fig. 28), when extended, forms a long sucto- 

 rial tube, and when coiled up represents a 

 flat spiral, like the spring of a watch. It 

 consists mainly of two modified maxillae 

 (see INSECTS). According to Newport, 

 each maxilla is composed of an immense 

 number of short transverse muscular rings ; 

 these are convex externally and concave 

 internally, and the two connected organs 

 form a tube. Within each there are one or 

 more large tracheae (fig. 28c*J) connected 

 with the tracheae in the head. The inner 

 or concave surface which forms the tube 

 (fig. 28 cf) is lined with a very smooth 

 membrane, and extends along the anterior 

 margin throughout the whole length of the 

 organ. At its commencement at the apex 

 (fig. 28/*), it occupies nearly the whole 

 breadth of the organ, ard is smaller than at 

 its termination near the mouth, where the 

 concavity or groove does not occupy more 

 than about l-3rd of the breadth. In some
