formation that it has befallen to me to find on the surface of 

 the water here about five stages of development of Limulus 

 rotiindicauda, wliich does not, like the North-American 

 species, according to Packard and Dohrn, directly develop, 

 but passes through a Naupliiis stage, with one, afterwards 

 with three eyes, wholly like a Phyllopod. A tail-spine is 

 present, but jointed above, and in this stage shows a parallel 

 with Euri/jJterus. Packard's mode of development is a con- 

 densed one ; and, as would appear, his, as well as Dohrn's and 

 Van Beneden's, generalizations on the position of Limidus are 

 throughout untenable, in so far as they remove this from the 

 Phyllopods [Apus and Branchqnis). They rather become 

 closely allied through their common Naiqdius with three 

 pair of appendages ; and a part of the ' Gigantostraken,' espe- 

 cially the EurypteridaB, should be added to them. 



" As soon as I reach Japan I hope to also examine the 

 Limulus there. The larvae here are unfortunately very rare 

 and difficult to isolate ; but I have good preparations of the 

 most important stages. I hope to fall in with the northern 

 species."
