Bather (2) describes peculiar covering-plates in the arm of Botryo- 
crinus ramosissimus : “ a large number of small irregular plates, which 
appear to extend beyond the limits of the groove itself over the adjacent 
portions of the arm-ossicles.” The author controverts the statement of 
Loven, Trautschold, and Wachsmuth, that slit-like fissures are present in 
the ventral sac (anal tube) of Botryocrinus. The columnals are divided 
by radial sutures into pentameres, which at the distal end of the stem 
have an hexagonal outline and an alternate arrangement. 
The author shows that the species of the genus form an evolutionary 
series, in which the characters that differentiate the species represent 
stages of individual growth. This series is shown to exemplify the 
origin of pinnulate from simply dichotomous arms. 
Under B. pinnulatus is described abnormal secondary arm-branching 
[*/. Bateson, Zool. Rec. 1890]. 
Bell (5) discusses the relations of the classes of Echinoderms to one 
another. The llolothurians are believed to be the most primitive, on the 
following grounds: (1) they are without a calyx (“ nomcaliculate ”) ; 
(2) the genital apparatus is bilaterally symmetrical (“ anactinogonidial ”); 
(3) the body musculature is well developed ; (4) in Synaptids there are 
ciliated funnels, and (5) in other llolothurians respiratory trees, both of 
which structures, the author suggests, are the remnants of a diffuse 
nephridial system ; (6) the water-vascular system is always continued into 
1891. [VOL. XXVJII.] F 2
