name could take. Ou the same page the unwarranted liheity is 

 taken of docking another such word ; and elsewhere tlic Greek origin 

 of Saccaynmiiia is falsified in " Saccamina." 



Doubtless this is a well-devised handbook, and, though limited 

 b}' conciseness of method, both in choice of typical fossils and in 

 treatment, it will be usr'fiil to students as a suggestive and trust- 

 worthy guide in palaBontology, especially as to the most probable 

 subjects to be taken up in examinations.

Colour whitish, or often deep purple above and whitish below ; 

 tentacles always deep purple. Length of my largest specimen (A) 

 is a little over 'Zh inches, but the body is in an extreme state of 

 contraction, and when alive probably the animal would have been 

 4 to 5 inches. Specimen 13 is also 2h inclies long, but scarcely one 

 fourth the circumference of the last, being fully expanded in length. 

 I now proceed to give an account of spicula of these and of a young 

 specimen. 



Specimen A, — liodj'-spicule ovate, with indented margin, having 

 four foramina, one foramen (oval) on each side and one (round) at 

 each end of a centi al bar ; a surface-nodule at each end of the bar 

 itself, and ten (rarely twelve) nodules on the margin of the spicide. 

 Upper small body-spicule campauulate ; height of bell greater than 

 or subequal to the breadth, upper portion of bell formed of four ribs 

 which arch down from the extremities of a very short central bar ; 

 near the mouth of the bell the ribs divide into two branches, which, 

 inclining right and left, unite with the branches coming from their 

 neighbours, and, just prior to their union, each branch throws out 

 downwards a little nodulous spur, so that the bell rests, as it were, 

 on eight little legs. This is the description of the type ; but slight 

 irregularities of growth often present themselves.
