724 The American Naturalist. [August, 
largely unprotected, collapsed in the dry specimens described. Pedun- 
cle rather short, not large, with small, sparse and separated conic scales. 
Height of capitulum 18, breadth at base 11 mm. 
_ The specimens described were collected by Mr. Frederick Stearns, 
and one of the cotypes is in his noble collection of Japanese inverte- 
brates in Detroit, Mich., the other being in the museum of the Academy 
of Natural Sciences of Philadelphia. 
The capitulum is covered with a soft dense pile, like S. villosum and 
S. trispinosum; but these are Pollicipeo-like species, very unlike sez- 
cornutum. From all other species of similar contour, the peculiar de- 
velopment of the whole lower whorl of plates as projecting horns, will 
readily distinguish this species, which is apparentiy nearer S. squamu- 
liferum Weltner (S.-B. Ges. Naturforsch. Fr. Berlin, 1894, p. 80) than 
any other described form. None of the forms described but not yet 
figured by Aurivillius (Ofversigt Kongl. Vet. Akad. Förh. 1892) seem 
at all similar. 
It may be mentioned in this connection that the Japanese species 
described by me in 1890 as Scalpellum Stearnsii was redescribed in 1891 
as S. calewriferum by my lamented friend Dr. Paul Fisher (Bull. Soc. 
Zool. de France, April, 1891, p. 117). 
It is likely that these “ horns,” while certainly inefficient as an ar- 
mour for the thoracic region, may be protective in function, as their 
acute, projecting points probably could not be comfortably masticated.

. The Orthoptera classified according to the characters of 
the Intestine.’—Continuing his studies upon the intestine and its 
appendages in the group of Orthoptera Bordas has made use of the 
facts in a classification of the group. The presence or absence of 
cecal diverticula permits him to form two suborders, Colotasia and 
Acolotasia, and the number and arrangment of the Malpighian tubules 
allow him to decide each suborder into several families. Seven families 
in all are recognized. Until the first suborder, Acolotasia, distinguished 
by the absence of cæca the two families Phasmide and Forficulide are 
placed, which under the second suborder, Colotasia, the following five 
families are distinguished by the characters and in the order given: 
(1) Blattidee by a well developed gizzard, eight cæca, and by the 
Malpighian tubes being grouped in six fascicles. 
(2) Mantide by a rudimentary gizzard and eight ceca, and by vol- 
uminous salivory glands.
