508 REPORT—1885. 
5. Altea ligulata, Busk, ‘ Brit. Mus. Cat.’ 
6. ,, Americana, V’Orb., ‘ Voy. dans l’Amér. Mérid.,’ D’ Orb. 
7. 4, argillacea, Smitt. 
Mr. Hincks says (op. cit. p. 3): ‘Seven species of Aitea have been 
described, of which three occur on our own coast.’ In the ‘ Challenger’ 
Report only one species is recorded as present in the material furnished 
to Mr. Busk (4. anguina, Linn.), and this was found at five of the 
stations: i. 36, 30 fathoms; ii. 161, 35 fathoms; iii. 135a, 75, 110 
fathoms; iv. 304, 45 fathoms; v. 162, 38 to 85 fathoms. 
Family II. Eucrateade, Busk 
= Eucrate (pars), Hincks, ‘ Brit. Mar. Poly.,’ p. 10 
= ScRUPARIADE (pars), ‘ Brit. Mus. Cat.’ 
‘Zocecium erect and free or decumbent, more or less ordinate. Zocecia 
uni- or bi-serial, or geminate, pyriform, with a subterminal oblique 
orifice, unarmed.’— Bush, ‘Challenger Report on Polyzoa,’ p. 2. 
In the classification of British Marine Polyzoa, Mr. Hincks places in 
his family the following genera—LHucratea, Gemellaria, Scruparia, Hualeya, 
Brettia, Dimetopia, and Clulwellia. As will be seen, only four genera are 
admitted by Mr. Busk, all of which are stolonate. 
Genus 2. Eucratea, Lamourouw. 
‘Zocecium usually with a creeping adherent base, erect branching. 
Zocecia calcareous, rising one from another singly. Aperture oblique, 
terminal or subterminal. Orifice semicircular, with a straight lower 
border. Branches springing from the front of a zocecium below the 
-aperture.’—Busk, ‘Challenger Report.’ (Mr. Hincks’s diagnosis is very 
similar to above.) 
1. Eucratea chelata, Linn, (Hincks, ‘British Marine Polyzoa,’ p. 14, 
pl. i. fig. 3; pl. i. figs. 4-8; pl. ii. figs. 9-11. 
2. Eucratea chelata, var. a. repens, Hincks, pl. i. fig. 3. 
3. 3 is » BP. gracilis, Hincks. 
Both Mr. Busk and Mr. Hincks limit, as above, the genus Hucratea, 
and only one species is described as British, but Mr. Waters (Bay of 
Naples Bry.) describes the following species, remarking that he ‘did not — 
find E. chelata at Naples, bet it is reported to have been found in the 
Mediterranean.’—Ann. Mag. Nat. Hist., 1879, p. 117. 
4. Eucratea ambigua, D’Orb. This species, which closely resembles 
FL. chelata, is a native of Sonth America. 
Nos. 1 and 3, Mr. Hincks says, are very abundant in Australia. The 
Species varies very much and ‘in an early stage of growth is often 
decumbent. A few cells are repent and adnate, and from these the 
erect shoots arise, and the zoarium then assumes its normal condition ’ 
(Hincks, p. 15). Eucratea chelata is the only species described by Mr. 
Busk in his ‘ Challenger’ Report, p. 3. 
Genus 3. Hippothoa, Lamowrous 
= CarENIcELLA (pars), Biainv. = Mout (pars), Smitt. ? TEREBRIPORA, 
D Orb.
