There is a very good series of this well known molpadid, the young 

 being in the Ankyroderma stage, and having many more, and much more 

 perfectly formed, tables than the adults. The largest specimen is over 

 100 mm. long, while the smallest is only 33 mm. of which 13 mm. is tail.

Molpadia musculus.

These specimens are small (the largest only 70 mm. long, of which 20 mm. 

 is tail) and two are in very poor condition. These two have minute, 

 scattered phosphatic bodies and some anchors and rosettes, and undoubt- 

 edly are the form called by Ludwig, Ankyrodcrvia spinosum. In the largest 

 specimen neither phosphatic bodies nor anchors were found.
