Five specimens quite typical from 2 cm. to 64 cm. in length, tables -09 mm. diameter. 

 In the smallest specimen the ventral feet are arranged quite distinctly in rows, 

 buttons average about '09 mm. in length and are quite separate from the dorsal papillae.

One specimen 36 cm. long ; light grey in colour with violet-brown spots (cf. 

 Sluiter) ; corresponds fairly to H. insignis Ludw., most of the buttons are somewhat 

 arched, the central rib being often in a plane different from and parallel to that 

 containing the sides and their surface is often uneven so that they approach the 

 condition seen in H. inhabilis Sel. The resemblance of the button-like spicules of 

 H. pardalis var. insignis to those of H. lentiginosa von Marenzeller (Rdsultats des 

 camp, scient. accomp. par Albert 1™ Prince de Monaco. Fasc. VI. 1893) may be 

 noted. The latter may possibly turn out to be a variety of H. p>(irdalis.

Two small specimens, 4'1 cm. and 2 - 2 cm. in length, belong to this species; the 

 deposits agree with those described by Theel; discs of tables vary from '1 mm. to 

 •04 mm. in diameter and spire varies in length considerably ; the tables with small 

 disc are provided as a rule with a short thick spire, while in the larger tables the 

 spire is narrower and longer and very rarely more than one transverse bar can be 

 seen ; the crown nearly always carries 8 teeth and some of the small discs are uneven 

 or even spinous on the margin ; the deposits seem to approach those normally found 

 in H. remollescens Lampert (fig. 5 a, b) ; the buttons, fig. 5 c, are occasionally
