Fetch as Google -- Does not result in pages getting indexed

[jplehmann]

I run a exotic pet website which currently has several types of species of reptiles. It has done well in SERP for the first couple of types of reptiles, but I am continuing to add new species and for each of these comes the task of getting ranked and I need to figure out the best process.

We just released our 4th species, "reticulated pythons", about 2 weeks ago, and I made these pages public and in Webmaster tools did a "Fetch as Google" and index page and child pages for this page: http://www.morphmarket.com/c/reptiles/pythons/reticulated-pythons/index

While Google immediately indexed the index page, it did not really index the couple of dozen pages linked from this page despite me checking the option to crawl child pages.  I know this by two ways: first, in Google Webmaster Tools, if I look at Search Analytics and Pages filtered by "retic", there are only 2 listed. This at least tells me it's not showing these pages to users.  More directly though, if I look at Google search for "site:morphmarket.com/c/reptiles/pythons/reticulated-pythons" there are only 7 pages indexed.

More details -- I've tested at least one of these URLs with the robot checker and they are not blocked.  The canonical values look right. I have not monkeyed really with Crawl URL Parameters. I do NOT have these pages listed in my sitemap, but in my experience Google didn't care a lot about that -- I previously had about 100 pages there and google didn't index some of them for more than 1 year.  Google has indexed "105k" pages from my site so it is very happy to do so, apparently just not the ones I want (this large value is due to permutations of search parameters, something I think I've since improved with canonical, robots, etc).  I may have some nofollow links to the same URLs but NOT on this page, so assuming nofollow has only local effects, this shouldn't matter.

Any advice on what could be going wrong here.  I really want Google to index the top couple of links on this page (home, index, stores, calculator) as well as the couple dozen gene/tag links below.
