Cape Verde-type hurricanes are those Atlantic basin tropical cyclones that develop into tropical storms fairly close (<1000 km [600 mi] or so) of the Cape Verde Islands and then become hurricanes before or upon reaching the Caribbean. Typically, this may occur in August and September, but in rare years (like 1995) there may be some in late July and/or early October.

Gulf storms are much different than Cape Verde storms. For one thing, they have a lot less distance to travel before they make landfall. Another is that they mainly threaten only the Gulf coast.

Gulf storms are also notable for their maddening unpredictability in terms of where they're headed. Often they meander around aimlessly, wreaking havoc with everyone's work schedules. Though late season storms tend to be weaker, that is not always the case. Let's not forget Opal in 1995 which reached Cat 4 strength before going ashore as a Cat 3 and causing great damage in the Florida panhandle.

Here is an excellent, if old, short article on the subject...actually it addresses hurricane season as a whole, but it is certainly apt for this discussion.
