BULLAA. 291 
I published in the 8rd vol. of the ‘Zool. Journal,’ I believe, 
twenty years ago, and have not seen either it or the animals 
since; I am therefore in some measure on new ground, and 
this oblivion is a guarantee that I am not influenced by former 
impressions.

Animal oblong oval, having the anterior lobe of the upper 
disk rounded in front, contracted behind, and in consequence 
showing its decided separation as to the groove from the pos- 
terior one, which is smaller and more subrotund, and contains, 
as in its congener, B. catena, the same shaped white vitreous 
shield, elegantly striated with oblique lnes composed of di- 
stinct dots; the posterior lobe bends to meet the pedal one 
beneath, and is slightly digitated, the left fillet beimg the 
largest, from whence the extremity gently obliques in an 
anterior direction to the right side. The pedal disk is con- 
tinuous, and meets the bent portion of the upper posterior 
lobe; it is also exceedingly well reflexed laterally, giving 
the characteristic four-lobed aspect of the tribe; the canal 
dividing the disks on the left side, is white and smooth ; while 
on the right, the anus, which is most posterior, then the pomts 
of the branchiz, and lastly, the common receptacle of genera- 
tion, may be seen, with the spermatic open groove connecting 
the last organ with the organe générateur; but I need not 
say more, as all these parts are identical with those of B. ca- 
tena, and are fully described in the references under that 
head. 
The pedal disk is pale yellow, suffused with a faint blush of 
cloud colour; the upper disk is of a dirty-white ground, but 
well marked with the finest longitudinal dark close lines, 
mixed with minute streaks and points, giving the whole area 
a dark cloud-coloured sombre aspect, instead of the pale red 
one of B. catena. 1 have a confused recollection that in my 
former account of this species I stated that I could not find a
