MELICEBTAD/E. 5 



yellow, strewed with round brown granules ; transversely striated on the inside ; foot 

 forked. 



M. Weber has drawn this Limnias with three antennae all on the same surface ' : 

 one long, un-paired ; and the paired two, short. As such an arrangement is unknown 

 in the Melicertadce, I have not reproduced his figure ; especially as he himself states 

 that all three are on the dorsal side. The foot, too, is described as " forked," and the 

 foot-glands as discharging their secretion through an aperture in the angle of the fork. 

 This structure and arrangement arc unlike those in the foot of any other Floscule. 

 The whole account requires confirmation. 



Length. Not recorded. Habitat. Neighbourhood of Geneva (Weber). 



LIMNIAS SHIAWASSEENSIS, Kellicott (181). 



SP. CH. Seven horny processes on the dorsal surface below the corona ; ventral 

 antennae long, nearly equal to the diameter of the tube ; tube slightly increasing in 

 breadth from below upwards, clear below, covered above by dark floccose, not smooth or 

 annulate, but beset with transverse parallel rows of minute raised points. 



Dr. Kellicott found this apparently rare Eotiferon, in July 1888, on Myriophyllum in 

 the Shiawassee river at Corunna, Michigan, U.S. It resembles cornuella in the length 

 of its antennas, but there are several points of difference in structure and habit between 

 the two. " The coronal discs, when acting, are not pushed so far above the tube as in 

 the other species the lower edges just clearing the margin of the tube ; the discs are 

 held nearly vertical, and the long ventral antennae stand out considerably higher than 

 the discs and at a sharp angle with the tube. The antennas are slender, nearly straight, 

 and terminated by a slender cone which bears a brush of setae ; when the lobes are with- 

 drawn, and the corona is just concealed, the antennae stand up above the tube, and the 

 extremity and brush of setae are then seen to be invaginated. The corneous denticles 

 [horny processes] are seven in number. In the middle line, just below the dorsal gap, 

 there are two arising from a common base, their apices are obtuse. On each side of 

 these, a little lower, is another with obtuse apex ; this pair points obliquely upward to- 

 wards the uppermost pair. Below these, wider apart, are two more, broad and set 

 obliquely ; and below this pair, near the middle line, is another pair, broad and set ob- 

 liquely. The cloaca may be seen thrust up to the rim of the tube, between these pro- 

 cesses, to discharge the faeces. The chin is obscurely lobed at its apex." (Kellicott, 

 loc. cit.}

CECISTES SOCIALIS, Weber (199). 



SP. CH. Body elongated; corona small, circular ; foot, twice as long as the body ; 

 teeth, three ; one ventral antenna ; two eyes in the young. 



This (Ecistes was discovered by M. Weber, in 1886, inhabiting a parasitic growth of 



profonde ") is meant the deep V-shaped cleft on the oral surface, at the bottom of which the lobes meet, 

 and the whole of whose edge is fringed with cilia, then the term "dorsal" is a mistake for "ventral"; 

 but if "echancrure " means the wide, non-ciliated, gap in the corona, between the lower portions of 

 the two coronal lobes, then, though the term " dorsal " is correct, yet the attribute " profonde " is 

 singularly inappropriate. Most probably the term " Echancrure " stands for the V-shaped cleft on the 

 oral surface, and for " dorsal cleft " we should read " ventral cleft." 



1 The text says that there are "two lateral tentacles," one on each side of the dorsal cleft (" Echan- 

 crure dorsale "), and, " lower down dorsally, in the median line of the body is one long dorsal tentacle." 

 An inspection of M. Weber's figure (PI. xxvii. fig. 4), however, shows at a glance that the long, unpaired 

 antenna is really meant to be on the same surface as the two, short, paired antennae ; for it intercepts 

 the view of the ventral (i.e. oral) surface on which the shortest pair are placed. Moreover, in the same 

 figure, the lower portion of the coronal lobe, on the spectator's right hand, is curved backward aicay 

 from him ; clearly proving tluit the surface he is looking at, and on which all three antenna? are placed, 

 is the oral, or ventral one.
