510 REPORT—1885. 
The only locality that I have the species from is Brazil. The slide 
came into my possession with others from the same locality, marked 
‘Membranipora, sp.’, and it was only after Mr. Hincks’s description was 
published that I was able tonameit. Lamouroux’s description of the form 
and also the locality given by him are as follows :—! 
‘ Pasithea tulipifera. Articulations in the form of clubs; cells three 
in number, united on one pedicle’ (‘ Corallina’), p. 67, pl. ili. fig. 7, A. 
‘ American seas, principally on the Jamaica coast.’ The other species 
described by Lamouroux is a hydrozoon. 
The only other genus of the Hucratiide of Busk is the following. 
I have adopted the diagnosis of Hincks :— 
Genus 5. Brettia, Dyster. 
‘ Zoarium erect, corneous, branched, branches given of from the top 
of a cell a little to one side, and facing in the same direction as the cell. 
Zooecia uniserial, elongate, subtubular; aperture, terminal or sub- 
terminal, large, with the oral valve at the upper extremity ; marginarmed _ 
with spines. Ocecia unknown.’—Brit. Mar. Pol. pp. 27, 28. 
1. Brettia pellucida, Dyster. ‘ Brit. Mar. Pol.’ p. 28 pl. iv. figs. 6, 7. 
‘ Quart Jour. Micr. Soe.’ vi., 1858, p. 260 pl. xxi. figs. 3-5. 
2. Brettia tubeformis, Hincks. ‘ Brit. Mar. Pol.’ p. 28 pl. ii. fig. 2, 
pl. v. fig. 1 = B. pellucida, Norman, ‘ Brit. Assoc. Rep.’, 1866, p. 
196, &c. 
The first of these species was found by Mrs. Brett at Tenby; a minute 
fragment of the second was dredged in The Minch by Mr. Norman. 
These are very rare forms, but anyone, after carefully examining the 
plates in Mr. Hincks’s work, can easily recognise the difference between 
the two species. 
3, Brettia australis, Busk. ‘Challenger Report,’ p. 7 pl. xxxiv. 
fig. 3. 
4. Brettia cornigera, Dusk. ‘ Challenger Report,’ p. 7, pl. xxxiv. 
fig. 6. 
As Mr. Busk by some oversight places the genus Brettia in two 
families in the ‘ Challenger Report,’ I have merely indicated its position 
further on by the number 26 ? so as to keep the synopsis and text intact, 
and preserve the suggestions even of the author. 
As to the numbered families and genera given in the Report, with the 
exception of Notamiide and one or two genera, which will be pointed 
out in the text, the whole of the present arrangement is that of Mr. 
Busk. As, however, Mr. Hincks has instituted several genera, and one 
or two families which are not accounted for, accepted, or referred to in 
the ‘ Challenger Report,’ I have thought it wise to include these in the 
several divisions, but wanwmbered. Mr. Hincks, therefore, is responsible 
for their position in certain families. His names will be found in his 
own synopsis—the second—in the introductory part of the present 
Report. 
1 The work of Lamouroux, referred to above, is his Corallina, translated by a 
lady. Hd. 1824.
